One of Opium Group’s smaller clubs, SET still has a significant following amongst jet set and Euro types. A luxurious lounge with chandeliers, a dance floor, and design mag–worthy decor is always full of trendsetters, celebs (Justin Bieber was partying here with his father the night he was busted for drag racing), and wannabes. Where you really want to be, though, is upstairs in the VIP areas. The door is notoriously tough; ask your hotel concierge to get you in.
