Master Chef Mario Batali visited Dalton's Popfood Class and snapped the accompanying pic as they prepared for last Saturday's amazing and sold out Popfood restaurant. Mr. Batali Instagrammed and tweeted the following post about his visit. "Mr Sloane's class @daltonschool prepping the pop up Saturday!!
