These Top Chef Masters competitors and long-time friends take the duel to a whole new level. Takashi challenges David with an ingredient for which he is well known, the egg. David reciprocates with a test based on crab that must be prepared three ways. Then for the Duel, guest judge Andrew Zimmern offers up some of the most bizarre ingredients for their meal. Having to cook with unfamiliar products will push these Masters to their culinary limits.

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.
