Mansion

SOUTH BEACH. Ensconced in a former Art Deco theater, this club is as vast and conspicuous as its name. Boasting typical SoBe panache, it's dressed with grand arches, chandeliers, sweeping staircases, Venetian mirrors and ornate fireplaces, is awash in glamour, and observes a velvet-rope policy, so come dressed to impress. Inside, four dance floors thump with music across three levels, and nine bars handle thirsty patrons. Lounges and VIP areas also find plenty of traffic. Moreover, celebrities are common, the level of sociability is enormously high, and top DJs definitely spin to please.
