Nostalgia envelops this Jazz Age haven for literary legends such as Dorothy Parker, Robert Benchley, and New Yorker creator Harold Ross. Al Hirschfield cartoons featuring Broadway plays hang over high-backed wooden booths, and the color of the upholstery lends this legend its name. The Blue Bar offers historical ambiance—the hotel dates to 1902—and is an elegant attraction for sophisticated imbibers. Lest you doubt that, ask one of the black-tie servers for the $10K ($10,000!) “Martini on the Rock,” complete with sparkly bauble in the bottom. Be sure to order it 72 hours in advance, which gives you plenty of time to have your head examined.
