The ideal boogie spots need a healthy balance of beats, grooves, funk—and personal space. While Hakkasan revelers shoehorn themselves into the movement-restricting dancefloor in the main room, the rest enjoy a more liberating shuffle inside the megaclub’s open-format side room, commandeered by pedigreed musical ringleaders such as Rev Run, DJ Ruckus and Questlove. MGM Grand, 702-891-3838. Thu & Fri, Sun, doors at 10 p.m.; Sat, doors at 9 p.m., cover varies.
