Cool dark place with a nice jazzy underground ambiance. They have live music everyday and an interesting food and drinks menu. The bands are generally diverse and professional. Usually, the cover charge is about 12-25$ per head. Only drawback is that they add the cover charge to your food/drink bill and demand to be tipped on the cover charge as well, which is a bit disappointing. Just increase the price of the entrance fee by 15% and do not demand tips on these fees.

Overall quite unpleasant experience. Cozy and beautifully decorated spot. Went to see some local musicians play on a weeknight, and were led to the back room, from which we could barely see the stage. We ordered drinks, and were promptly told that we needed to order food as we were taking up space from other patrons who would be willing to pay more to sit there. There were multiple empty tables and there was certainly nobody being turned away. There was a cover charge which we were happy to pay and we were planning to order more drinks and tapas as well. We were spoken to very rudely and gruffly. Another man came to our table to tell us that there were empty tables nearer to the stage but that he would not allow us to move to the front room unless we ordered food. We felt extremely uncomfortable. We proceeded to order more drinks and food and we continued to be treated rudely by the staff (and were not moved to the front room). Immediately after the show was over, as we were about to ask for the cheque to leave, the waiter informed us that if we wished to stay longer we would have to pay the cover fee again (we were very clearly leaving and had already spent a quite significant amount of money to sit there and enjoy the music for 1.5 hours). The music was fantastic, as was the food. I understand of course that the restaurant has to make its margins but we felt as though we had been wrung dry. A last addition is that I feel it is bad form to charge the cover fee for the musicians on the table bill, as the tip from the cover should go to the musicians and not the wait staff, especially when their attitude is so demeaning.

A beautiful small spot for Jazz lovers in Montreal! If you’re looking for positive vibes and energy then this is your place. Friendly staff and the drinks are good!

Great jazz bar. However be careful about reservations. If you don’t reserve in advance you might find a table from which the stage is not seen. Cocktails are acceptable.

Forget the jazz, go there for the food! Steak was absolutely amazing. Quite possibly the best steak I’ve had in my life. I’m pretty cheap but i’d go back every week and pay the $40 to eat it again…also go there for the jazz.

Great atmosphere and service. Perfect jazz bar. Intimate. Great sound. People were totally respectful to listen. Didn't eat there. Staff was excellent.

Live jazz resto-bar. Always great musicians playing here, different themes depending on the day of the week. Located in the basement but very cozy. Excellent service and great atmosphere. A must visit for any jazz enthusiasts.

What a wonderful night, Mondays with Alex Bellegarde Latin Jazz Quartet. The service was great, authentic servers who care about you. The menu is simple but creative. The T-Bone steak was huge so it’s definitely worth the price. Wine suggestion was perfect. I can’t even describe how great the energy of the musicians was, they include you in their positive vibes, make you sing, dance in your seat. Perfect date spot and a great way to relax after a long monday at work for sure! Can’t wait to go back.

One of Montréal's few Legendary Jazz Bars that are still in business after the Golden Years have passed (ended approx. late 90's), where you can regularly go watch the "Crème de la Crème" of Jazz Musicians, mostly Local (Montreal) and visiting artists (from around the Province and Abroad). Besides the Upstairs, the Dièse Onze (french for sharp eleven/ #11 for you musicians out there) is the "other" great Jazz Bar. Technically, it's a Resto/Bar, and you can eat decently to relatively well there, but be warned: the Food is seriously overpriced. Not to a ridiculous point, but still, you'll want to stick with the cheapest items on the Menu (like their Burger) if you don't want to end up paying 50$/person, UNLESS you don't mind and/or want to treat yourself, maybe to celebrate a special occasion. But still, if your goal is to eat amazing food, you can find absolutely mindblowing food at other places for the same price or less. I want to emphasize that I am in no way saying that the quality of the food is sub-par, or not to eat there! No! I just wanted to let you know what to expect in terms of pricing. It's pretty solid food! As for the Bar side of things... there, you're in for a treat: they've got a rock solid selection of great Beers, Wines (including various Champagne), Liquors and Drinks. You can pick your poison of choice and you'll be satisfied, at any price range! Lastly, I wanted to talk about the Hosting and Service. The Dièze Onze already has so many strengths, but one of the best part of the experience (besides the music, of course), is the way you're treated by all staff members. They are all genuinely happy to be there, to serve you, they're EXTREMELY polite, classy, knowledgeable and always smiling. If you're having a really bad day, are depressed, interacting with the staff/waiters is bound to lift your spirits! There's also the decor, which is fitting for a small Jazz joint located in a basement. To help you better visualize what comes next, I'll briefly give you the layout of the place. It's pretty much a rectangular room (although the dimensions make it close to a square), and the room's width is a bit less than its depth. Except for a small reception area in front, the center of the room is occupied by the bar, running along the depth in such a way that it separates the room in a left and right side. The scene is located at the back of the left side, in such a way that the view is completely blocked by the bar for anyone who's sitting on the right side space. This is my only gripe about the place, as it's already pretty small, and if you come for a show, I STRONGLY ADVISE you to make reservations well in advance and ask for a table as close to the scene as possible, because if you end up on the other side of the room, you're pretty much screwed... The owners are obviously well aware of this problem since they've installed a TV there to stream a view of the scene... This might be ok for some, but for any music aficionado, that's unacceptable and a total deal breaker! When you go out (and pay the ticket) to go watch a live music concert, it sure as hell isn't to watch it on TV while the Guys are playing right next to you! So. All in all, especially since it's one of the best Jazz venues in town, I find Le Dièze Onze to be a truly magical place, well worth going to! As long as you're aware of its 2 setbacks ($$$ Food & Blocked view of the scene) and take the appropriate measures to sidestep the 2nd issue by making sure that you get a table on the left side, you'll be more than fine with all this venue's other great features, especially the impeccable service from the staff! With the proper precaution/prep, you'll be guaranteed to be in for an amazing experience!

Fantastic bar. Excellent service, wonderful live music, cozy atmosphere and food to die for. We had poke bowls, scallops and the best rib of beef ever with amazing crispy potatoes. We came for the live jazz but were blown away by the unexpected high end cuisine.

In general, all in the table agreed on giving 3.5 of 5 points. The service, good. The waiter, of course, gently pushes you to order food... it is his job 😉. The food we ordered was good but nothing special and a little bit expensive for the quality and for very common tastes. Concerning the jazz, first I have to say that we don’t know too much about jazz, we are just amateurs who like certain styles of jazz more than other. That night during the show we saw a lot of happy faces who seemed to be enjoying the music. In our case, we didn’t like the style, it was too quiet for us. If we would come again? Considering that you pay a cover of $15/person, for the show and because of quality and prices of food the answer is... maybe but only to take some drinks with one or two tapas and to listen to a different group.

Latin jazz night blew our minds. Definitely glad we stayed for the second set! Service was great, just one waitress holding it down all night like a true professional. Food needs some elevation to be on par with the music honestly, but drinks were great and our evening here was a highlight of our week in town. Would suggest some more gluten free food options for sure.

Basement jazz club. Reservations strongly recommended, at least for the weekend. We came on a Saturday of the Labor Day long weekend and all of the seating, including at the bar, with visibility to the band was full. There was also seating without visibility that was mostly empty.

Cozy spot to catch live music. Romantic enough to bring your date for a nice evening. Affordable ticket prices, and we were accommodated even if a little late. Great sound quality, and strong drinks. Fun night, and would be back!

We came on the night of Christine Jensen Quartet. Great music. The place is small under street level which it makes it cozy and gives it an intimate feel. We furthest from the stage but we still enjoyed the show. The food was excellent. Everyone in our party enjoyed it.

Nice cozy ambiance, limited formidable menue, we tried burger and Salmon tartar and both were great. Good choice of beers, reasonable price. The only drawback is entry fee of 14$ per person when there was is a performance that tax would also be added to that. If you don’t want to have dinner and just want to enjoy the music and have beers, you should go for the 9-10 performance. (7-9 pm you should order dinner)

Amazing atmosphere and music. Wonderful place to people watch. I didn’t love my cocktail, I’d order a beer next time. Also quite affordable.

Don’t miss it if you re a jazz lover. Great ambiance. Intimate and Cosy place. Excellent staff. Food is savoury with generous quantity and cocktails as well.

We had a wonderful experience here. We had a late night dinner and stayed for the jam session. If you are looking for an authentic cool jazz experience, this is the place to go. The music was great. We’re looking forward to going back again.

Make sure you go here on a Sunday night for the best jazz performance. Get there a little early so you can get a good seat. Meals are a little expensive but totally worth it. The patrons are really nice and helpful. Fluent in English and French

My experience at this location was not pleasant. Waiter didn't deliver menus, he literally threw them on the table. When we were ready to order, my girlfriend and I decided to share one of the dishes. The waiter should have warned us that the dishes would come in minimal portions for just one person, this would have made the biggest difference during dinner and, of course, in the service provided. The only positive point was the band that was playing. Poor service, expensive food, tiny portions. I do not recommend.

Very nice intimate atmosphere. Incredible band playing that night, didn't get their name. I'm from Toronto so my partner and I drove to Montreal for a vacation. Will definitely visit again!

Live jazz music every night. Super talented musicians! My favorite is Latin Jazz in Monday night! Food is good, and cover fee reasonable!

The food and service were excellent

Great sound equipment, great jazz musicians in town, quality food (have you tasted their risotto? wow!), affordable beer… One of my favorite spots to hang these days.

Was a nice concept a bit cramped for the type of venue/idea they want to accomodate. The waitress was at first abit not friendly or approachable but appeared she was too busy for the night. She ended up being nicer near the end, perhaps because it was time to tip by then? Was okay but was a bit thrown off by the initial staff impression. I am sure there are other jazz experiences in MTL aside from this one.

So many great musicians come through here. Always a treat! The Miles Davis Kinda Blue evening was sensational.

Expensive, garbage drinks and super entitled waiter wanting lots and lots of money in tips. Very few places I've been where you pay premium for garbage. Save yourself 100$.

With the closure of Biddle's, it is nice to see Montreal still has a great venue. Small in size (intimate), but huge on delivering a great experience. Dropped in and it exceeded expectations. Had the chance to sit next to some Jazz students who were visiting with their music professor and ended up meeting Gary, the owner. Can't say enough about this place...great food, a very reasonable price for a nice bottle of wine...and an exceptional live band. Didn't try their beers...but the tap list looked great

Went here last night with my son. Both of us had a fabulous time. We arrived about 30 min before the show without reservations. It was our first time here and we hadn’t realized that they were a good idea. We were told that we would be seated at the back and moved in time for the show if there were any no shows. We both had the halibut (which was very tasty!). Turned out that we were in luck. And after dinner, a few minutes before the show, we got moved to wonderful seats right in front of the state. The performance was fantastic. All in all, a lovely evening in a great venue.

Was in Montreal for the night with my son and found this place. What an awesome experience. Alex kudos to you for the jam session!

A bit to pricey for the quality. The French fries were not the best. The place however hosts live bands on Mondays and that's worth the 4 stars. Great vibe, great music, great people!

Food was good, amazing musicians. But I couldn't enjoy 100% because people were talking too loudly.. from the tables in front of the kitchen.. if you can get the table or bar near the musicians, it'd be perfect to enjoy the music.

Great venue. Very cozy and cool vibe in this place. Great music and live jazz performances. The food and wine selection are exceptional. Not to be missed in Montreal!

The band is good. Drinks and ambience also good but I don't like being confronted and demande to tip 15% for the cover charge which was $30 added on to the drinks price. Cover charge shouldn't need to be tipped as there is no service provided. If you think the cover charge should be more then charge more so I know what I'm getting into. The bartender was just the owner anyways so I don't see why he needs to be tipped if he owns the place.... He also asked in a rude and demanding tone.

Incredible jazz! Also would recommend the linguine pasta with duck confit

Wonderful spot with quality live jazz, food and drinks. Ensure that you reserve for dine-in and the band! All is worth it. Food is exquisite, not pub level (hence, a bit more pricey). Staff is very respectful towards patrons and the band as well. There is a good vibe in this place. One leaves with a smile on their face.

i love this place. the service could use some sharpening up, but the music is excellent, the ambiance is respectful of the musicians (it's a place folks come to LISTEN to music), and the food is solid and reasonably priced. in Covid time, the tables are still quite (too?) close together with no barriers, so if you're a worrier, this may not be the place for you.

Jazz bar with the best local (occasionally international) jazz. Check website for listings. The food is amazing. I had the tuna tataki and it is top class. Drink menu has good selection of whiskeys and gins.

Intimate jazz bar-restaurant. Service was friendly and food delicious. Had the honour to see Kim Richardson, one of our greatest voices.

Concept is nice. We went for the live jazz. It was ok Bar wasn’t very clean Smelled of stale old beer and urine Drinks were not good Servers were busy and not overly friendly Overall not our vibe

Beautiful establishment with a great live music shows starting from 7:30pm and 9:30pm. There is $12 cover charge if you go for shows. They have a good alcohol menu with a lot of choices for different liquors and wines. I enjoyed their burger very much. It was juicy and the cheese added a great flavour. I forgot to check carefully on the menu, but it was probably brie or camambert. Salmon tartare and beef tartare has 2 different options; tapas portion or meal portion with salad, potatoes and croûtons. I don't know if the tartare itself would be in different portions or the meal means + salad and potatoes. Monday night has Latin jazz live music which was great to dance salsa in tiny spaces between the tables. You need to be careful and in control not to bump into other clients or tables so you would not be the bad annoying client 😂 I would definitely go back again.

I am really amazed with this place. Everything was way above average, like ambient, food, options of drinks, service, sound quality, and, of course, Kim Richardson Trio performing on Sunday, that by itself would deserve a sixth star in this review . Kim's voice and interaction with the audience is something unforgettable. You guys got a new fan! I definitely recommend this place.

The music is the most important part and it's usually pretty good. Way to go to help keeping the local jazz scene alive. The food is pretty good too so it works very well as a normal outing place too. Has a good vibe all the time.

Large, tasty portions! We split a plate and had a couple of drinks. Walked away full. The server expertly attended all patrons. This is a must-visit bar for good service and food. We loved the jazz music too. Beautiful saxophone performance.

We loved this place! They have great music combined with a cozy, authentic jazz bar atmosphere, and attentive, relaxed service. I would absolutely recommend to anyone who loves great jazz, and suggest making a reservation if you are interested in going on a weekend evening. The venue is small and intimate, yet didn't feel at all cramped which is great! It's down a set of stairs from the sidewalk so be sure to map it or you might miss it. Enjoy!
