Duff Goldman turns the Triple-G Flavortown Market into Sweet City on . Guy Fieri has handed the keys to his grocery store over to dessert master Duff Goldman and given Duff carte blanche to remodel the store, restock the shelves and sugarcoat his grocery games. Each week Duff will test the skills of a new batch of four pastry chefs as they race the aisles shopping, preparing, and plating confectionary creations in three rounds of epic baking challenges.
