Guy Fieri tracks down some great places that prove fast food can also be great food. In Fairhope, Ala., a where a trained chef is doing fast food the old European way -- pressed panini sandwiches, filled with everything homemade, even the mozzarella; in Austin, Texas, homemade tacos done every which way -- from breakfast, to carne asada, al pastor, fish tacos, and more -- and even the salsa is made from scratch; and in Gilbert, Ariz., a fast food joint right on the farm, where they're growing much of the menu out back, and the burgers and pizzas are made and topped with the freshest ingredients.
