If there was ever a place to go at that point in the night in which everything turns wonderfully weird, Sligo is it.
There's writing etched into all of the surfaces, it's a little grimy, super narrow, and the beer is cheap. I love walking by and seeing people in their during the day: it's so amusing to me given that I don't think I've ever passed through those doors before 11pm (and that's being generous).
All in all, this is a no frills dive. If you aren't choosy about atmosphere or like that sort of authentic, local bar feel, I'd give Sligo a shot.
I'm giving it 3 instead of 2 b/c it wasn't as packed as the other places (Saturday night at 10:30pm) and the beer was cheap. Not a big menu, but I liked what they offered (can't go wrong w a good UFO) - and it was $4!
It is a small place w bathroom doors that don't lock. But instead of a jukebox they have a giant iPod-looking thing on the wall. That's pretty cool. I like technology. We're getting close to Star Trek, where everything is a touch screen.
Anyway, cheap drinks and jukebox of the future
