When two chefs known for their tempers face off, it is bound to get hot in the kitchen. First, Dale challenges Tiffani to relive a past failure of hers in preparing dim sum. Then Tiffani counters with a contest based on an American canapé and classic cocktail. For the Duel, featuring guest judges Rob Zombie, Scott Ian, and Gary Holt, the chefs must prepare a vegan meal and service will get hard core as one Chef will be rocked. These Top Chef All-Stars are out to prove that the third time's the charm.

Two chefs are back to set the record straight. Jen and Nyesha were arguably sent home before their time on their seasons of Top Chef. Now these women are back with a vengeance. First Jen tests Nyesha's familiarity opening and preparing sea urchin, and then Nyesha challenges Jen to confront a past demon from the show, mastering bacon and eggs. For the Duel, the chefs break the law for the cast of Brooklyn Nine-Nine. Underestimating these chefs would be criminal.

This is the ultimate showdown between the only two female chefs to ever win Top Chef. First, Stephanie challenges Kristen to take it to the streets Thai style, while Kristen pushes Stephanie out of her comfort zone and into fine dining by making an upscale pasta dish. Then for the Duel, it's a clash of rustic versus refined cuisine as the chefs lock horns in a showdown of biblical proportions themed around the Garden of Eden.
