This historic theater up in Hongkou was once a temple, then it was Chinatown, now it's a bubbling club/lounge/bar regularly hosting cabaret theater shows. It's a really beautiful old space with a gallery and theater boxes, with a real feeling of history in the wood, but the management have done a good job turning it into a modern venue. Think Moulin Rouge, but from the movie. It's a bit out of the way, but don't let that put you off, there's almost always something going on there, from tribute concerts to movie screenings to talent shows and more risque acts. Note that it's a full-service bar, so under-18s aren't allowed in during evening acts.
