This trip, Guy Fieri's goin' back to some DDD flavor-makers for a mess of meat and Mexican! First, an old-school deli institution in Chicago is busy as ever, fillin' up food trays with killer corned beef hash and mouthwatering meatloaf. A Cincinnati street taco joint has expanded big time, with new menu faves like craveable carnitas taquitos and sizzlin' stuffed poblanos. Plus, a Cajun smokehouse in New Orleans has really taken off, mixin' it up with the-bomb boudin grilled cheese and an over-the-top chopped chicken sandwich.
