We had a poor experience here. The service was slow despite being not that busy. Server walked by the bar 3x without grabbing our drinks and we eventually got them ourselves. Food was just ok. My salmon and sauce were cooked perfectly and delicious but my partner's steak frites was not, apps were nothing to write home about. The whole menu lacked creativity and classic French staples. The art in this restaurant was atrocious and generally the decor was dated. The whole place seems in need of a refresh, especially the bathrooms. It had been a 100 degree day so we opted to eat inside but it was warm and stuffy. Overall, this place is marketed and priced as a 'nice' or 'fancy' restaurant and it is neither. Wishing I had spent my date night elsewhere.

Came here for dinner after reading about it being one of the best places for dinner. We were not disappointed! The weather was great so we sat outside- much quieter and less crowded than indoors. Our server told us about the specials of the day that we’re not on the menu, and needless to say, half of our meal was from specials, and the other from the everyday menu. We ended up getting the Burrata and French Onion soup with Gruyère as the first part of our meal. They were both delicious and the perfect size, leaving us satisfied, but definitely hungry enough for the main course. Speaking of, our main dishes were the Lamb Bolognese and the Mussels. I was not a fan of the pasta, but my dining partner loved it. The mussels were the star of the night, though. There was quite a lot of them and the taste was immaculate! I recommend this for anyone visiting Boulder and looking for a place to eat out (it was very reasonably priced as well)!

Good food and good service. We sat outside on their very lovely patio. I had the chicken with frites, which were perfectly cooked and a salad that was also delicious. My husband had steak and frites which he said was the best steak he had had in a long time.

I’ve been here a few times and the food/cocktails/wine are excellent. The service has always been slow but it’s usually been worth it. Unfortunately I have to amend that because no matter how good the food is, if you don’t get utensils for 20 minutes after the food comes, or your cocktail order doesn’t come out for 40 minutes(and then is wrong) it doesn’t matter. I really hope service gets better and I can change this review.

Better than ever.. My experience here in years past has been “like a box of chocolates“… But there is a new captain at the helm, Matt Yule, and what used to be the case of “you never know what you’re going to get“ with service and quality has become a consistently awesome experience, time after time. This is now my shamefully frequented go-to neighborhood spot where I can count on consistently stellar service, great food, and a wine list that never fails to impress (pro tip: ask for Griffin; wine-guide-extraordinaire who’ll never steer you wrong).

I don't want to be harsh, but: I ordered a pâté from Mateo on Aug 3, and the next day (Aug 4) I developed diarrhea and still have not recovered from it to this day (Aug 7). I do not have any prior underlying stomach issues; I just returned from a road trip across Colorado, during which I consumed a pâté dish from a local French restaurant in Canon City and had no problem whatsoever. I would like to remonstrate against this restaurant's handling of food, and seriously suggest anyone who comes across this post refrain from visiting this restaurant, or at least do not order their pâté, as there are potential public health issues.

Boulder's multi decades of experience in fine dining !! Charming location with outdoor seating right on Pearl Street. There is plenty of street parking in front or half a block south on 19th. This icon has had long-term management and a staff who clearly enjoys working at Mateo. Delightful drink menu with unexpected selections. Plan on ordering food again and again when you experience what they offer. Highly recommend the Tomato Bisque, my favorite I've ever had. My evening meal was poulet frites, chicken served with fondue and hand cut frites. If you are burned out on chicken, please consider this dish! Organic slow cooked pan seared, it is unforgettable. Salad was delicate, absolutely fresh. Fries came out hot, this mael takes about 20 minutes. Lemon tart to finish, went nicely with the last sip of the recommended white wine in photos.

A great find in Boulder. The food..service and friendly staff were all amazing. Please add this restaurant to your wish list... Its so worth it

The mussels tasted fishy and bitter, and the risotto was undercooked. And in tiramisu, the water came out. What the hell is going on? Only the server was friendly. It was a restaurant I loved, but I don't think I'll go there anymore.

Thoroughly enjoyed everything about this establishment. So glad that my fiancé and I found this spot, not only is the atmosphere comforting but the staff was so kind, helpful and made us want to come back even before we had received our dishes. The food was delicious and prepared beautifully, will definitely be back in the times to come! Sadly it was a bit dark by the time we got the entrees so the photos aren't as clear but trust and believe, it was exquisite.

It was just ok which was really disappointing since we were very excited to dine at Mateo. Our server was new which is totally understandable. We dined early and we’re there for the happy hour menu. We had the butter lettuce salad (regular menu) which was very good. The dressing was perfect. We also had the steak frites and the moulles from the happy hour menu. The steak was tough and definitely not what I would expect from a Provençal bistro. The moulles were good. I’d eat those again. We finished with the lemon tarte and the panne cotta both of which were average. I was surprised by the number of Italian wines on the list since it’s a Provençal restaurant. There were no white or rose French options. With all of the great restaurants on Pearl St we have lots of options which means each restaurant has to be top notch. This one didn’t perform .

Very nice food preparation and pleasant ambiance. Not too formal but with many good elements to enjoy the food. It is one of the casual mid-high end restaurant. Maybe not fancy but great place to go.

A solid French bistro style restaurant. It's super busy so things can be a little chaotic in there. The food is delicious, the steak frites was delicious, they use a lot of pepper on the steak, which made a good crust . The bread and cheese were decent, I wish there was a little more of each cheese but it was enough to get a few bites each. The mussels were tender, delicate and full of flavor. For somewhere so far from the ocean I'm glad to see the they tasted fresh. Whilst it's not kid friendly, I would not say it's unfriendly. I do not think there is a kids menu. So consider that if you are bringing kids. I'd definitely go again.

An extraordinary evening with a dear friend. Started with plump moules- delicious in a savory tomato and wine broth - followed by the poulet which was out of this world - succulent and extra crispy at the same time. Matt treated us to the gorgeous and as equally delicious green Charteuse digestif to perfectly top off the night! Can’t wait to come Back!

This a great place.Local restaurant with an amazing menu. People working there are really nice and friendly. Went with my wife, seated at the bar and had an amazing moment

I'd never been to Mateo, but it was a very pleasant experience. We arrived at 6p and the only spot they had was the shared table which was no issue. They menu was pretty small, but all the food looked good. I ended up with the Lamb Bolognese, it was good not great. The server was knowledgeable about wine and did offer a good suggestion. I'd go back once the menu changes.

Great experience overall - tasty drinks and every dish was delicious and well balanced. We were initially worried about being seated outside (it was less than 40 degrees out) but the patio heaters kicked in quickly.

I met up with a friend from the Honey Pot next door and whilst it was late and Mateo's kitchen was about to close, Aidan said "don't stress, come on in" which we were kind of bloody well thankful for as we were STARVING! A great wine and liquor selection, and the Lamb Bolognese and Duck Konfit were spectacular. Wonderful service by Aidan, Annabel, and Leo and they even let me stay inside whilst I waited for my Uber for 25 minutes as it was absolutely pelting down outside. 1st time here and we were very impressed. See you again soon.

By far the best burger in Boulder. The sweet smothered onions knock it out if the park. Can’t thank Griff enough for the great professional friendly service. Highly recommended!

Tasha was my bar tender and host. She took care of us to a level that I've never experienced before. She attended to every request we made promptly and even gave us special options that weren't on the regular menu and nearly read our minds about what we wanted. This venue is also zero waste which I greatly appreciated. I think I'll strictly eat here whenever I'm in boulder.
