45x4 - Diners, Drive-Ins and Dives

This trip, Guy Fieri's diggin' into all kinds of Italian. In Santa Barbara, Calif., Dennis Miller is riding shotgun for a taste of prime-time pizza and amazing arancini. In Las Vegas, a vegan joint is puttin' their spin on an Italian "meat" sandwich, plus a funky pizzeria is stuffing chicken parm into a spectacular stromboli.
