Guy Fieri's headed back to some Triple-D hot spots gettin' saucy and smashin' out the flavor. First up, a Minneapolis pizza joint is still spinning out prime-time pies like a white-sauce chicken, not-your-everyday pepperoni, and gourmet pork banh mi. Then, a neighborhood staple in Boston is still puttin' out lights-out lobster rolls, along with a mega meatball sub and a top-tier Tuscan wrap. Plus, a gangster gastropub has moved to a new space in Waltham, Mass., plating mouthwatering mushroom poutine and out-of-bounds onion smash burgers with a kick.
