This is my absolute favorite night spot in Vegas. The piano players are amazing and so talented. They play everything from Neil Diamond to AC/DC and don't sound cheesy. I am always entertained. It's not as wild as some Vegas places and while it tends to attract an older crowd everyone has a good time. I believe the pianos start at 9pm but I like going around 11pm when there are more people. There isn't a cover charge so you can check it out and leave if you want.
The negatives are the drinks are very expensive and the waitresses are slow. I don't think it is their fault I think they are just understaffed.
