Rio Suite Hotel (51st Floor)
Cover: Varies
The Voodoo Lounge is probably the hippest place in town. It attracts upscale locals and tourists alike with a smooth atmosphere and music like Lenny Kravits, Collective Soul, Alanis Morresette, and even some Andre Bocelli. The view of  Las Vegas from 51 stories up is beautiful (in that Vegas way) and the large patio section allows you to enjoy the night air. Late night menu available.
Catch Jimmy Hopper while he's playing at the VooDoo lounge. He's absolutely terrific!
9pm to 3am, every Wednesday through Sunday.
