1. Fizz Champagne Lounge, inside Caesars Palace: While the Champagne may be good, the view is even better as pieces from Elton John and David Furnish's personal photography collection adorn the space. (Furnish is the lounge's creative director.) Katy Perry bought the place out (max standing capacity: 150) for New Year's Eve and John brings his friends after his concerts at the Colosseum. "Nobody has really tried to own Champagne in Las Vegas, so here we are," says Furnish.
