Metro Diner (Jacksonville, FL), Parkette Drive In (Lexington, KY)
This trip Guy's going where viewers sent him. In Lexington, Kentucky, a restored 1951 drive-in that's still serving the same double burger that made it famous. In Jacksonville, Florida, a diner in an old soda shop, scratch-making a menu that goes from meatloaf to stuffed French toast. And in Minneapolis, Minnesota, a breakfast joint celebrates 60 years as a neighborhood favorite.
