Ultimately, the food does the talking, as one-by-one the losing chefs "check out," by a rotating panel of judges that includes Melissa d'Arabian, Richard Blais, G. Garvin, Troy Johnson, Catherine McCord, Aarti Sequeira, among others. The last chef standing goes on a shopping spree of a lifetime worth up to $20,000!
