We've seen Guy Fieri's son Hunter grow up on Diners, Drive-Ins and Dives, Guy's Big Bite and Guy's Grocery Games. Now, his high school graduation gift is the ultimate food-filled adventure: a month-long trek through Europe. Guy and Hunter make their way through seven countries to experience the age-old traditions behind many international foods we've come to love, like gyros, feta, Parmesan, prosciutto, croissants, pretzels, paella, fish and chips, and more.
