Diners, Drive-ins and Dives

Rollin' in the Dough (28x7)

:

On this trip, Guy Fieri is diggin' into dishes featuring some dynamite dough. In Mesa, Ariz., a legit Hawaiian joint serving island specialties, including a meaty bun, and in Tucson, Ariz., a place cookin' up a big-time saucy sandwich and spinach dip calzone. Plus, in Miami, Fla., a funky shop making sweet artisan doughnuts and turning their pastries into savory sandwiches.
