As the New York City Wine & Food Festival's "Down South Up North" dinner wrapped up last night, three of the featured hosts circled up to tweet about the Southern food-filled evening. It all started when Ted Lee (@TheLeeBros) snapped a Twitpic of his chili crab on the menu. (His brother Matt, the other half of the Lee Bros. duo, was somewhere nearby feasting on the crustacean.) Chef Art Smith (@chefartsmith) jumped in to type: "The Chefs and Twitter!!xooxArt." And barbecue pitmaster Chris Lilly of Big Bob Gibson Bar-B-Q in Alabama just played along. He doesn't actually have a Twitter account.
