My latest fantasy? A Peking Duck cart, set up smack in the middle of Times Square. I can't stop thinking about it; there's a place out in Flushing that sells wonderful squares of crisp duck skin tucked into little buns with scallions and a squiggle of Hoisin sauce for a dollar. It's a luxurious snack, and if you set one up in midtown Manhattan there would surely be lines around the block.
