If you are ok with a place that claims its a gay club, check scandals. Even though its main focus is the homosexual factor, its a really fun place to dance and everyone is always nice. It doesn't have that sleazy, trying to pick people up for one night stands feeling. Plus if you are going with your girlfriends you wont have to worry about being hit on a ton!
As for bars: My favorite was always the yatch club. But there are several right in that area. And of course some nights are just better than others based on the crowd. Also check out the bier garden. You can play guitar hero and such there if it interests you.
