The Ghostbar is also in the Palms Casino and is a lounge, rather than a club. Having said that, they do have DJs at the weekends, and the small seating area quickly becomes a dance floor. This lounge is very small and has a space-age feel to it, with modern furniture and lounge chairs, as well as funky, futuristic chairs strung up like hammocks to relax in.
You enter this bar by an elevator, and that’s the only way you can get in. The wait when we were there was 2 hours, but as we had eaten at N9NE, I think they gave us preferential treatment and let us go up when we showed our dinner receipt. I’m not sure if they always do this, but it's worth asking. I heard some people say they had waited the weekend before for 4 hours!
On getting out of the elevator, the other three walls are all glass, and so the view of all Vegas is worth the $10 cover charge. There’s also an outdoor patio which has a glass floor, so you can see the ground 55 floors away. Don’t venture out there if you are afraid of heights, though plenty of folk were dancing away on it without a care.
This is the bar you often saw on The Real World when MTV did the Vegas show. It's also often featured in the magazines as a favorite place for Britney (pre-baby) and the Hilton sisters. Of course, I bet they don’t have to wait 4 hours.
