I first heard about them from Anthony Bourdain of course, and the motion was seconded by a friend in Queens. So whenever I'm in New York, and I go regularly, I've stopped at one of their locations - lately the newest one on St. Mark's Place, but also the original in Flushing and the Chinatown/LES branch. I'm always amazed how much good food I can get for under ten bucks. Is there anywhere in the DC area that serves anything like their liang pi (cold noodles) or lamb burger?
