Returning GGG chefs are ready to contest their defeats by taking on their former Flavortown rivals in three winner-take-all grudge matches worth a guaranteed $5,000 each! In the first grudge match, two chefs who were originally forced to team up go head-to-head in a decadent dinner challenge using only ingredients that start with the same letter. In the second grudge match, two chefs from Guy Fieri's Summer Games are back to make a fine dining dinner featuring the ingredient that caused them headaches in their original match-up. In the final grudge match, GGG judge Duskie Estes is back to redeem her surprise loss to fellow judge Troy Johnson by creating a California dinner using nine items or less.

Three pairs of twins team up to show that two head chefs are better than one at winning up to $20,000 in Flavortown! First, chefs who share the same birthday have to turn birthday cake ingredients in a delicious dinner. Then, the remaining family duos roll a pair of dice to determine the crazy culinary restrictions for their "classic duo" dish.
