This is not "an authentic Irish bar". It is authentic in that it is inexpensive, fabously no frills, and Irish themed. My favorite aspect is the lack of TVs everywhere - this is a place you go to DRINK. And it's one of my favorite bars in the financial district. You meet interesting people with a thoroughly unpretentious mix. Dollar draft is Natty Ice, and they have a couple craft brews on tap, but the $2 bud light is what most people see as the value-play. I've eaten here twice, and while I'm reducing the snootiness of the post, both were, frankly, disasters. But I'm giving it a good review because the people, inexpensive drinks and authenticity of it are THAT good. Sure, service can be hit and miss and it can be loud, obnoxious and a bit rough around the edges, but if you're looking for one of the top dives in the city where it doesn't get jammed-packed and you can open a book and read/chat in obscurity, I think this is THE place. 4 out of 5.

We came in with a large party and had a blast. We were served immediately with friendly bartenders and a fun atmosphere. One of our favorite bartenders, Paul, had many drink suggestions. Not one person in our party was disappointed. I highly recommend this bar. Always ask for Paul if you want the most out of this experience.

We went to this bar because of a friends recommendation but we were gravely disappointed. The bouncer on July 20th was completely unprofessional. My friend was clearly 21+ with a VALID Massachusetts drivers license and the bouncer took his license and told him to call the cops if he would like it back. We had to get it verified by two other workers to get his drivers license back and into the bar. And don’t even get me started on trying to order a beer once we were in. They were very rude to us during the whole process! I definitely would not recommend this bar, unless you are looking to get harassed by a bouncer.

What a nice surprise! Happened on this place at the end of our trip. It’s nothing special at first glance but the service was great and the food was, too. The bartender was a really nice guy with a great sense of humour. Cheers from your Canadian friends and Go Habs Go! XD

An Tain is perhaps one of my favorite dive bars to go to in Boston. It is tucked away in the downtown financial area however it has perhaps some of the best drink prices. They have combination of whiskey shooters and beer for 10 dollars along with 1 dollar beer. No better deal in the city.

Kind of grungy. They have oversized games though that are loud but super fun. Played giant connect four for hours with friends. Large open space. Smallish bathrooms but clean. Definitely had the best prices in the area, beers I think were five bucks when I went. Great place for groups.

Went to Coogan’s with a few friends but the bouncers there were giving us a hard time and we left. Walked around the block and found this spot, and I’m really glad we did. Extremely casual setting, and $1 house beers with no cover; you can’t beat that in Boston!

Great place! Friendly staff. Dollar Coors light, Fast bomb food. When you order Cajun fries, they automatically bring out waffle fries. What's more to love?! 5 Stars all day.

Great little local near the harbour. Great Guinness and only $6 for a true pint (20oz). And house darts available if you forget to bring your own.

I've been here a few times and it's really hit or miss. Once they had some of the cheapest beers in the city (I'm talking 1$ pints) making this place awesome, but we went back a different time and the same drinks were super expensive and the place was just overall fraty. Not really my scene.
