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.

The final three all stars face off in an epic Italian showdown to cook the meal of their lives in an effort to take home the ultimate title and prize.

In the Quickfire, the chefs play a game of telephone with their loved ones as they try to reproduce the dish their family member is eating at a nearby restaurant; the chefs create a signature product that they will bottle and sell at a food festival.

With only six chefs remaining, the challenges get even more difficult, when pastry super-chef Sherry Yard awaits the all stars for a dreaded dessert Quickfire; chefs endure a blindfolded taste test to pick their ingredients.

Tom makes his final decision from "Last Chance Kitchen" on who should return to the competition; the chefs take off in a Quickfire with Padma and Jonathan Waxman making a two-course business class dish for an airline.

Comedic superstars Ali Wong and Randall Park swing by the Top Chef kitchen for a Quickfire Challenge tasking the chefs to make the wackiest fried rice they can; then, the chefs head to the famed Getty Museum to seek inspiration from the art.
