This trip, Guy Fieri's grabbing all kinds of grub, starting at a funky little Italian joint in Wilmington, Del., serving outrageous arancini and veal scaloppini. In San Diego, a Middle Eastern street food spot slaying with shawarma and first-rate falafel. And in Vancouver, British Columbia, a not-your-typical pizza place toppin' things off with lamb sausage and pig cheeks.
