The former Pure was a game-changer in its era of local nightlife, so it’s fitting that Hakkasan Group’s total revamp of the Caesars space takes things to another level. The highest tech, the biggest sound, the most exclusive club-within-the-club (Heart of Omnia) and a posh terrace space—not to mention an unquestionably super-powered stable of resident DJs—all come together to make Omnia the place to be in 2015. Caesars Palace, 702-785-6200.
