I've been here a handful of times and each time it's been either completely empty or super-crowded. Each time I've gone there has been a cover at the door, and the drinks have been a bit pricey. The crowd is a bit older (people in their 30s seem to frequent there) and the crowd also doesn't seem quite as friendly as other places. It's a place worth going at least once to experience it (go in the summer, they have a great patio).
Pros: Live music a lot of nights
Cons: Pricey drinks, older crowd
