NOT that I'm a super hip Vegas night club connoisseur, BUT, I felt that The Bank was not up to par with the many other choices we have here in Las Vegas. For my money, I'd rather hit up Drais across the street which is where I'd say The Bank competes with.
The dancing area is somewhat small compared to other clubs and most of the space (understandably) is occupied by private table service areas. That said, if you're going to float the cash for table service, I'd probably look at another club.
A plus is that you can probably get into The Bank after 11pm without a HUGE line if you don't already have VIP access to one of the other clubs in town.
You can certainly have a great time The Bank and the service at the bar is good.
