The lounge area at this much-loved rock 'n' roll club generally features local bands, with the occasional showcase by up-and-coming major label signings. It also exhibits work by local artists, and serves pizzas, salads and sandwiches. But the larger, two-tiered back room is where the real action happens. The view-blocking support pillar just in front of the stage? Well, that's just character building. Given the caliber of bands performing, this is one of Boston's must-visit rock haunts.
