Four GGG winners return to Flavortown for a big burger battle. First, Guy Fieri requires the chefs to squeeze all the ingredients for their international burgers into tiny shopping bags. Then, in a burger-themed game of shuffleboard, the chefs pick unusual items to use in their unconventional burgers. Finally, they're randomly assigned a cheese for their gluttonous cheeseburger, and the competitor with the better burger goes on a shopping spree worth up to $20,000.
