If you've ever wondered whether that one scene from Martin Scorsese's "The Departed" was filmed here, don't worry: Within 20 minutes, somebody in the bar is gonna tell you about it. Jokes aside, this well-preserved and surprisingly spacious relic from a more elegant-looking--if less civilized--era of Brooklyn bar history stands as a proud testament to the enduring power of wit and whiskey over common sense. As the name suggests, this is an old-school Irish bar through-and-through, and a haven for those who claim Ireland, either as their actual home country or via the questionable decisions of some long-lost immigrant ancestor. This establishment is also one of the last holdouts of a rapidly dying New York breed: the bar that still opens at 8 o'clock in the morning. Come for the unscathed early-20th-century wood decor and the perfectly poured pints of Guinness, and stay for the World's Surliest Bartender (You know who you are) who, on particularly prickly nights, is his own source of entertainment. There are also various events, including an open-mic music night, and a great jukebox packed with the kind of old Irish ditties and (slightly) less-old classic rock and punk standards you would expect from an establishment of this ilk. As with all authentically New York bars, the Haven can be a mixed bag when it comes to clientele, and to its attitude toward non-regulars in general. It can get quite packed at night, especially on weekends. And if you don't absolutely love the sound of a pack of shouty pink bros in matching Islanders jerseys and 2-for-1 Supercuts, maybe check the evening's sports listings before you come out.

I had the pleasure of hosting my Birthday party at the Irish Haven, renting out the back room. Matt, the owner, was very responsive and super easy to work with. The keg we reserved had definitely had the lines cleaned which I really appreciated and everything else was a good price. Very happy overall and hope to have more parties there in the future!

Yes. The best bar in Brooklyn!!!from the bartenders,to the locals,And even the owner.All down to earth and very welcoming

Great atmosphere and customer service. Very fun and their Guinness is the best !!!! Go check it out.

I was here for a surprise party a couple of days ago. I felt welcomed. What was really cool was they had photos of The Departed. I would totally come here again.

This is one of best spots I've found in Sunset Park! Love the charm, quality service and you can't beat the prices. We had a great time. We particularly enjoyed the friendly locals and the attentiveness of the bartender. Can't wait to come back and try to catch some of the live music or trivia.

Had a wonderful time today. Friendly folks, great atmosphere. Stopped in today and was immediately treated like an old friend. This is a real New York bar, for real New Yorkers. God I miss going to bars. #savr
