So I have an answer for planet Earth, and it's Teatro in Switzerland. The first line in my TUSCL review was "This is one of the coolest clubs in the entire fucking world." The rest of it's over at
tuscl.net.
As I think about an answer, hindsight is playing a role because I'm trying to separate my experience from the objective pros and cons of the club. Twentysomething wallanon was looking at things differently than the same guy decades later. The answers I've seen here mostly sound like great options, but to me the coolest club is a place I'd hang out in even without smoking hot chicks minus their clothes. That's a very short all time list, and in 2021 it's a list of zero clubs. Throwing that factor out, then I think of places like Casa Diablo in Portland, OR. A place with personality. As much as I like the style of a place like Palazio in Austin, TX, it's still cookie-cutter and I've seen a hundred other places trying to put on that big time GC character.
Casa Diablo's not my pick, at least not yet, and I'm also thinking of places from when I first really got into the SC scene in the 2000's that were in decline but still had some of the old mojo left. Like MBOT in San Francisco. It was going mostly on reputation even then, but my first visit was still pretty mind blowing because it was room after room of temptation with top flight talent. Or Spearmint Rhino Vegas, that to me had a cool factor the other major clubs in town didn't. As I'm typing this, BELAX in LA is also coming to mind as still being in the conversation. Also 4Play, but I prefer BELAX. But then there's that GC template, and does 4Play really break the mold? Actually, it's been a while since I thought about LA and there's some standout clubs there. Maybe my answer is somewhere in Southern California. But whatever, if I can get to a list of ten clubs then I'll just pick one of those.
