The luxurious grand opening of The Cosmopolitan Las Vegas began with a cocktail hour complete with an ice champagne and oyster bar, followed by a four-course meal in the Condessa Ballroom. The space was transformed into a stunning, modern VIP supper club with the use of a fringe proscenium and purple lighting. Guests danced to live performances by Jay-Z, Florence and the Machine, DJ Coleman and Mavis Staples on a metallic, silver vinyl dance floor beneath 50 disco balls.
