This trip, Guy Fieri's going from Portsmouth, New Hampshire to Portland, Ore. for righteous coast-to-coast flavor. In Oregon, a Spanish spot serving outrageous octopus and an homage to the chef's childhood. Plus, a multitasking market sandwiching polenta and cookin' up grandma's take on biscuits and gravy. And in New Hampshire, a modern cantina puttin' out the pork, from belly tacos to a pig's head platter.
