OK, and also spinning roulette and I think a little craps too. Small place but of course, busy. Went on a Wednesday night and coughed up twenty bucks to get in. Definitely an experience as you have LCD screens showing off Playboy covers and other photos, but no nude shots. Only shots are at the bar. Surprisingly a lot of female attendees and I guess you can draw your own conclusions there. Was surprised though some of the bartenders were guys! At the Playboy Club? Doesn't Vegas have enough decent female barkeeps?
There's also some video poker and slots as well. Not to mention one of the best views of Vegas you'll ever see. Definitely bring your camera if security doesn't try to confiscate it.
