I've had an amazingly good time every time I have gone here.  Most recently was for the Scion closing party for SEMA.  The bartenders know how to make stiff drinks and it didn't help that it was open bar.  The music was great and although it is crowded it never seems to be so packed that you can't dance like it sometimes is at Tao or Pure.  I like the VIP tables that overlook the dance floor.
