This is a decent place to go see various types of electronic dance music.  It's not an insane place that will make you want to vomit or gouge out your eyes (i.e., Myst, et al).  The times I've been here, the people here seem pretty decent, though there is the share of ridiculous folks. 

The bar service generally isn't very good, and you can expect to wait a while to get a drink.  The place is pretty small, so if you're seeing a big act, you will be tightly packed and wait a while to get upstairs (one up - one down when filled).  And be wary, you're liable to get second-hand pepper sprayed from one of the neighboring bars/clubs.  The bathrooms are small, and the Men's has no door on the stall (gee, I wonder why...).

On the plus side, the music is usually good, and they stay open past 2AM (wtf is with you people and "liquor laws"?).
