Friends of 15 years face off! Italian wunderkind Sal Marino of Il Grano and La Bottega in Santa Monica challenges old friend and former "Knife Fight" judge Mark Peel. After the closure of his restaurant Campanile last year, Mark is hungry to redeem himself on the L.A. culinary scene. To get it done, he'll have to use English peas and tendrils, sea snails and venison better than his seasoned opponent. See if they remain friends after the decision!
