Fifteen of the competition's fiercest challengers return to face-off in the toughest season yet! A mise-en-place challenge set at the historic Griffith Observatory in Los Angeles kicks off the intense battle, where the Chefs immediately size each other up to see how everyone has progressed since last competing. Then, the first elimination challenge takes the Chefs to the beach to cook a seafood meal -- however, their only heat source will be fire. No electricity, no special appliances. Back to basics. It's going to be a true slug-match to see who has the skills and who has the drive to take the one thing that has eluded them all... the title of Top Chef! Padma Lakshmi, Tom Colicchio, and Gail Simmons return as judges and joining them as the first guest judge of the season is legendary Chef, Jeremiah Tower. Marcus Samuelsson, Nancy Silverton, Michael Cimarusti, Josiah Citrin, Suzanne Goin, Caroline Styne share the table for the high-powered, high-stress beach-side meal.

It's Restaurant Wars and this season Padma takes all the limitations off the table as the chefs can make as much food as they want and shop wherever they choose. The two winning chefs from last week's concept challenge are given 48 hours to pick their teams and make the restaurants they pitched come to life.

This week the chefs honor the late, great Pulitzer-Prize winning food critic Jonathan Gold. Using Gold's last guide list, the chefs fan out all over Los Angeles to sample the unique taquerias, food trucks, mom-and-pop cafes, upscale eateries and ethnic cuisine only found in the City of Angels. Drawing inspiration from this one-in-a-lifetime culinary odyssey, the chefs create dishes to serve 200 of Jonathan Gold's friends, family, and restaurateurs that he loved at the iconic Union Station. Noted food writer and personal friend of Jonathan Gold, Ruth Reichl serves as guest judge alongside Padma, Tom and Gail.

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 one of four historical art movements to create a masterpiece on their plate. Guest Judge Ludo Lefebvre joins Tom, Padma and Gail, as well as guest diners Chefs Ray Garcia, Sara Hymanson, Sarah Kramer and Craig Thornton.

In the Quickfire, it's a true test of communication as the chefs play a game of telephone with their loved ones as they try to reproduce the dish their family member is currently eating at a nearby restaurant. Then, the chefs are tasked with creating a signature product that they will bottle, use on a dish and sell at a food festival. They may get help from their visiting loved ones, but for one chef, the help won't save them from being sent home. Celebrity Chef Nancy Silverton is the guest judge joining Tom, Padma and Gail.

The chefs are challenged to a taco throwdown for the taco king, actor and restaurateur Danny Trejo. For the Quickfire, the only sharp tool they can use is a machete, in honor of one of Danny's signature characters. Then, Padma informs the chefs that the only way to make it to Restaurant Wars is to survive this week's qualifying challenge. The cheftestants have to dig deep to create and pitch a restaurant concept complete with a couple of dishes to the judges -Padma, Tom and Gail, along with "Top Chef" Chicago Winner Stephanie Izard and James Beard Award winning Restaurateur Kevin Boehm. The top two concepts will be the restaurants built for the signature Restaurant Wars challenge, while the chef with the judges' least favorite concept will be eliminated.
