NEW YORK (AdAge.com) -- In a marketing effort aimed at luring well-heeled consumers back into high-end restaurants, Zagat and sixteen New York City chefs are traveling back in time, sort of. Called the "Vintage Dinner Series," the new campaign has the restaurants serving up historic 19th-century meals for 21st-century prices as high as $575 a head. The menus feature cuts of meat, game and specialty foods like mock turtle soup or baked Alaska that, over the last century, fell out of favor with American diners.
