Sure, but the OP asked for fun things to do.
FLYMSY mentioned a few of the classic music venues, but the one that really stands out is Rock 'n' Bowl. Have you ever heard of "cosmic bowling"? Well, cosmic bowling is lame, but if you replaced the cheesy light-and-sound show with awesome zydeco music, big crowds of friendly dancing people, and lots of cheap booze, it turns out it would be awesome.
