I think that Parliament House is now the big one.
Pulse and Savoy - Ive been to each once but don't remember them much.

the club part of PH is fun depending on the night. And I love that they have a separate drag show bar inside, so you can dance or catch a show. Where as at most clubs the drag show takes over the dancefloor and if you don't want to watch the show you have to wait till its over to dance.
The rest of the PH "resort" is kind of scary/sketchy. It's very cruisey! I mean if that's your thing you'd love it. I have friends who love PH for the easy pickups. LOL
