Robert Irvine is cheating with sinfully good slices! In Wayne, N.J., there's a pizzeria serving up 15-pound pasta-stuffed pies and eye-popping dessert pizzas with colorful icing, cookies and chocolate. In St. Louis, they're taking the art of pie to new levels with gooey multi-pies and pies baked inside of cakes. Finally, in San Antonio, Robert indulges with award-winning shredded beef, birria on cheesy flatbread, and a spicy ceviche tostada with shrimp prepared two ways.
