The Restaurant Wars challenge comes early but first the chefs duke it out in an amuse bouche-based Quickfire; with 12 chefs remaining, three restaurants battle for victory; Tom makes an announcement that leaves the chefs breathless.

The drama of the Restaurant Wars challenge continues as Tom announces a double elimination; chefs Karen Akunowicz and Nina Compton join the restaurant crawl along with Nilou Motamed and guest judge Caroline Styne.

Lena Waithe surprises the chefs with a challenge to make their best version of a trademark Kentucky dish; Nancy Silverton brings a special challenge with her.

Chef Art Smith judges a fried chicken blind taste test; the chefs try to impress guest Laila Ali with dishes inspired by her father Muhammad Ali.

In Kentucky, 15 chefs are off for the the ride of their lives at Churchill Downs; the chefs must make a dish that will appeal to a crowd of 200 at a Kentucky Derby party; Churchill Downs' own chef David Danielson serves as guest judge.

The chefs honour 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 food trucks, mum-and-pop cafes, and ethnic cuisine.
