Glitz. Grandiosity. History. The Diamond Horseshoe, a reinvented palace of pleasure that boomed during the 1940s, is back and better than ever. Guests descend down a majestic spiral staircase and into a huge ballroom, with multiple bars and stages, where dancers and performers contort and sway in a seductive series of spectacles. The space hosts the hit dinner show Queen of The Night, an interactive evening of cuisine and spellbinding cabaret (see www.queenofthenightnyc.com for tickets). Weekly dance party "PrettyUgly" (every Sat., 11 pm-4 am) draws a young, hedonistic crowd (fashion insiders, nightlife names, Brooklyn art scene) to the luxe, larger-than-life space.
