Inside, there will be two bars and several booths for seating and space for live entertainment. Part of a multi-part transformation at the Summerlin casino, the new bar is the latest move as the property pivots to amping up its nightlife scene.Ī large gold door flanked by velvet curtains leads to the bar’s red room with a grand piano at the center. Rouge Room takes over the 5,345-square-foot space that used to be the Crimson, which hosted seasonal pop-ups like Crimson in Bloom and Merry Crimson. A new European-style bar is opening at Red Rock Casino and Resort with swanky red velvet, floral martinis, and caviar.
