In the premiere episode of Bravo's "Top Chef," the cast will be thrown straight into the demanding kitchen of famed San Francisco restaurant Fleur de Lys for the quickfire challenge. In the individual elimination challenge, the chefs must prove that they deserve to stay in the competition by cooking up their signature dish. Guest judge Hubert Keller (famed chef and partner of Fleur de Lys) joins host Katie Lee Joel and judges Tom Colicchio and Gail Simmons to help to make the decision on who must "pack up their knives" first.
