Guy Fieri's gettin' into flavors from all over! First up, a Vietnamese spot in Boston is dishing out rockin' rice noodle rolls and a barbecue beef banh mi on fresh-baked baguettes. Next, there's rustic country-style Italian in Missoula, Mont., plating up a legit lamb meatball sub and knockout octopus. And in Minneapolis, a Panamanian chef is cookin' up a taste of the Caribbean with big-deal beef skewers and jammin' jerk chicken.
