Watch Guy's Grocery Games Season 17 Episode 13 Online

Four chefs are given one chance to shop for all three rounds -- and they have no idea what they're being asked to make. First, Guy Fieri asks the chefs to make their best lunch. They'll then have to use their remaining ingredients to make an international dish featuring a surprise ingredient from the international aisle. Finally, the chefs must use the ingredients they've saved to make their best refined dinner. Only one chef will out-cook the others and earn a shopping spree worth up to $20,000.
