The final three chefs attempt to earn the title of "Top Chef."

The final four chefs compete in Napa Valley to determine who will be the final three.

The chefs are challenged to a taco throwdown for Danny Trejo; for the Quickfire, the only sharp tool they can use is a machete; the only way to make it to Restaurant Wars is to survive this week's qualifying challenge.

The chefs head to the mountains outside of Los Angeles to go to a summer camp where they are challenged to an outdoor grilling Quickfire for Padma and "Top Chef" Kentucky winner Kelsey Barnard Clark.

Contestants visit Craft Steak in Las Vegas to cook for actress Natalie Portman and friends.

The chefs host a "Pig and Pinot" event at guest judge Charlie Palmer's Aureole restaurant.
