The contestants face a challenge in which they prepare sushi.

The 13 remaining contestants are asked to make food for everyday people: beach goers and firemen.

Only three potential Top Chefs remain, and this episode's quickfire challenge will test their ability to get creative with junk food to make a tasty dish that could still be served to conscientious diners. On the other end of the spectrum, the next challenge gives the chefs a shaving of white truffle, a rare fungus that retails for two thousand dollars a pound. They must use this tiny, but revered fragment of fungus to create something delicious for some of Napa Valley's most respected chefs. Featured Napa Valley chefs include: Phillippe Jeanty of Bistro Jeanty; Keith Luce of Press; Greg Cole of Celadon; James Devitt of Budo; Cindy Pawlcyn of Mustards Grill; Victor J. Scargle of Julia's Kitchen at COPIA; Doug Keane of Cyrus; Todd Humphries of Martini House; and John Ash of John Ash and Co.

In the fifth episode of Bravo's "Top Chef," the chefs are blindfolded, fed rare ethnic cuisine, and then must identify the ingredients. They then hit the streets of San Francisco for the elimination challenge where each team must serve a variety of fusion dishes from handcarts and will be judged upon taste, creativity and customer satisfaction. Helping to judge this episode is Mike Yakura, a well-known culinary figure in his hometown of San Francisco and chef for the famed French-Asian Fusion and Vietnamese restaurant, Le Colonial.

Bravo's hit culinary series "Top Chef" is back with 15 rising chefs, one red-hot Los Angeles kitchen and some of the restaurant industry's most renowned talent. In the premiere, the chefs dive straight into the heat with their first quickfire challenge where they have 30 minutes to shop for ingredients, flamb their dish and present it to the judges, including "Top Chef" season 1 winner Harold Dieterle. The winner of this flamb challenge will have immunity for the elimination challenge, where they will face their toughest critics. New to the judges' table this season is host, Padma Lakshmi, who joins Head Judge, Chef Tom Colicchio of New York City's Gramercy Tavern and Craft Restaurants and Gail Simmons of Food and Wine Magazine. Harold Dieterle, who plans to open his Manhattan restaurant Perilla later this year, will guest judge and help determine who stays and who must pack their knives to go home.
