Avoid at all costs.
I have been treated with more respect from muggers. The service is absolutely horrible, and the servers are very rude. The bouncer, the chap with the chin strip and an excess of 60 pounds, is pushy, foul and actually curses you out (I think I even detected him say something anti-Semetic under his breath. AVOID THE UNDERGROUND Bar at all costs!!!!
Fun but a little crowded.
Whiskey is a good place to go early in the evening if you just want to hang out with your friends. It also a good palce to go later in the night when you want to let loose and dance.
