Restaurant Wars

In the most anticipated challenge of the season, the chefs are put to the ultimate test. Not only will they have to build restaurants from the ground up, but the Chefs' Table is back. If that wasn't enough pressure, "Top Chef's" signature challenge levels up yet again, requiring the chefs to satisfy their VIP counter and a dining room full of guests watching their every move in an open kitchen. Guest judges Tiffany Derry and Hunter Lewis join Padma, Tom and Gail on the battlefield.
