600 Fifth Avenue, Gaslamp
This is a fantastic place for showing off your dance moves. If you don't want the entire intersection of Fifth and Market watching you shake your groove thing, you'll need to find a place away from the floor-to-ceiling windows that wrap around the dance floor. Or free your inhibitions first by sampling the 20 beers they have on tap. The bar runs the length of the place, so there's no cramming into one spot to get a drink. You'll find live music, from blues to disco to reggae, with different themes every night of the week.
