Great place. The dance floor is excellent, lower than the rest of the place with seating at the sides. Even when crowded it can be fairly easy to move around.
Only complaints: the bar service was a bit slow last night, and the coat check is on the 3rd floor meaning you have to climb a crapload of stairs to get your coat. If you're drunk and have a coat there, you'll be screwed.
The show last night was only $10 at the door, fairly regular prices for beer.
