The final team of four chefs face a food group they typically avoid for this week's Quickfire: they have to re-create a junkfood classic (Season One, Top Chef).  Michael Chiarello (Bottega Restaurant), Rick Moonen (RM Seafood at Mandalay Bay), Nils Noren (French Culinary Institute) and Lachlan McKinnon Patterson (Frasca Food & Wine) are then put on the spot as they are pushed to make the perfect three-course mini-meal. Flipping Out's Jeff Lewis and Jenni Pulos guest star, and one chef moves on to the Champions Round.

Knives are drawn and the display of extraordinary talent begins in the most ordinary of places – a grocery store where the chefs are met with the classic Quickfire "Aisle Trial" (Season 3, Top Chef). Master chefs Roy Yamaguchi (Roy's Restaurants), Art Smith (Table Fifty-Two), Michael Cimarusti (Providence) and Jonathan Waxman (Barbuto) pass the Quickfire round and are faced with a mystery box from which they must concoct their Elimination Challenge meals. One chef moves on to the Champions Round.

The top six chefs have advanced to the finals and now must face-off for the ultimate title of Top Chef Master. Each is asked to produce their signature dish, only to find they must then re-create their competitor's unique dish. One chef is eliminated, while the remaining five move to the next round of competition.
