This is one of the best places for dancing in Madison. From the few times i've been there, it's never been too crowded, but it's also never so empty that you feel like there's a spotlight on you. It's usually at a good enough level where you have space to do your thang. The music itself is interesting, as it's usually live DJs catering to a different theme every night. I've heard several different types, such as house, latin, and juke. It's a very refreshing change of pace from the usual top 40 or standard EDM you may hear at other bars.
Drink wise, it's good. Reasonably priced beers, and a small selection of specialty drinks to get you going as well. The few i've had have been tasty.
I don't have any valid complaints about this place. Note though that if you aren't there to dance, then you're not likely to enjoy yourself. It's what this place is built for.
