In the battle for the title of "Hottest Nightclub in Las Vegas," the focus has been on new, hip, original, and exclusive. Moon works that angle, while its sister Playboy Club does something new by going retro, turning a known brand on its ear and turning it into something still relevant in the new millennium.

Located atop one of the hotel towers at The Palms, the two clubs are distinct yet linked together by an escalator, elevators, and the long lines and high cover prices required to get in (an eye-popping $40, which merely gets you in the door).

The Playboy Club, located one level down from Moon, is a retro-chic version of Hugh Hefner's mansion, with clubby nooks done with stone and wood wall treatments, new-millennium takes on leather wing-back chairs, and flat panel monitors over the fireplaces instead of paintings. Throw in the dozens of cotton-tailed servers and you have a deliriously over-the-top take on the Playboy mystique, complete with gaming tables to bring out the 007 in you. A tuxedo is not required, but you almost feel like you want to throw one on, grab a martini, and throw the dice with one arm while you put the other around a girl wearing bunny ears.

The crowds are epic, the drink prices sky-high, and while the rooftop locations offer great views, waiting for those elevators to make your entrance or you escape are a pain in the cotton-tail. Still, this is the kind of club that makes club-going entertaining again.
