City: Las Vegas
Address: 3708 Las Vegas Blvd. South
Infinity pools? Check. Four-story LED screens? Check. Badass roster of performers? Check. It's not hard to see why the esteemed Cosmopolitan's day/nightclub has become an overnight celebrity among nightspots. Tiered coliseum-style seating offers everyone situated at the tables in the main room a solid view of the DJ and dance floor residents, while the Boom Box and Library enable guests to switch gears and take in some hip-hop or curl up with an assortment of Vegas-themed books in a more intimate setting. The cocktail waitresses dressed as sexy bookworms also don't hurt.
