Club M in Laguna Beach (South OC) - fine ass girls, dress nice or you won't get in.
Costa Mesa has quite a few spots too, Club Vegas(expensive), Shark Club, Detroit Bar.
The Boogie in Anaheim had it's moments but they lost they're liquor license last week, so that shit might be dead.
I'm more of a bar person myself, but there's all types of different spots in So Cal.
