Guy Fieri's Diners, Drive-Ins and Dives buddies roll up to Guy's turf for a challenge of a lifetime. The chefs must first knock down crazy food pins to pick the ingredients to put between two buns! Next, they must make tacos after all the traditional taco ingredients are thrown out of the window in Un-Gredients. The final two chefs will go to their roots when Guy asks them to make a finer diner dinner using an item from both the high end and low-end food wheels.
