You'd have to define 'club' but one of the best venues was the old Skrappy's in Tucson. Rad green room completely open for doing stencils and graffitti backstage, they had a snack bar (all ages no alcohol kinda place, which was the only downside) smoking area, etc.
The thing that made it cool though was that it was open as a youth center all day every day, and it was all volunteer, or rather user-run, so it had a really cool vibe. The people are what made it, tons of kids would show up to see ANY kind of band, and they'd get into it. One of those rare, open-to-new-stuff islands, know what I mean? The sound was great and the stage was great too. And it was right by the hotel Congress, so you could just walk across the street and have a drink at the bar of the hotel where Dillinger got caught.
For sheer atmosphere/decoration, AND with a bar, CIA in North Hollywood. You can search for pictures online but you don't get 1/100th of what it actually looks and feels like. It's the creepiest, weirdest, most rad little spot ever. It's like a circus sideshow on acid.
