This trip, Guy Fieri is diving into all kinds of comfort cooking. In Phoenix, there's a funky joint stacking up barbecue fries and putting a new spin on chilaquiles. In Boulder, Colorado, a pizza place loads up the pies and their meatball grinder. Plus, a Dallas spot cranks out all kinds of off-the-chain chicken.

On this trip, Guy Fieri is digging into dishes featuring some dynamite dough. In Mesa, Arizona, there is a legit Hawaiian joint serving island specialties, including a meaty bun, and in Tucson, Arizona, he stops at a place cooking up a big-time saucy sandwich and spinach dip calzone. Plus, in Miami, Guy checks out a funky shop making sweet artisan doughnuts and turning their pastries into savory sandwiches.
