Flatbush Avenue, Brooklyn
Now, I don't know if this is nightlife, necessarily, but it's definitely a place to go just hang out and have a few beers. This bar is great, but not for everyone, I don't think. If you are looking to meet someone or hook up for the night, then this isn't the place. If you're looking to avoid covers, have good conversation and feel a little bit like you just walked into Cheers and you're Norm, this is the place to go:) The music is great--it's older stuff--they even have the "Mob Hits" CD collection--you'll hear Frank, Patsy Cline, Clapton, CCR, lots of things from the 50's/60's. And these people have been going to this bar forever...great neighborhood stories about how Brooklyn used to be. And there's dancing...take a look at the picture:)
AND, often someone will go on a food or cigarette run for you...you can trust these people.
Dress Code: Haha, you could walk in here with a bathrobe and I don't think anyone would care. Clothes are probably a good recommendation.
