That's Italian

Diners, Drive-Ins and Dives

Pizza Palace (Knoxville, Tenn.) • Hullabaloo's Diner (Wellborn, Tex.) • Four Kegs Sports Pub (Las Vegas, Nev.) This week Guy sets out to find great Italian food in places you'd never expect: pizza, pasta and meat sauce at a Knoxville drive-in; a Texas diner servin' up Italian sausage-pepper-and-onion hoagies, Philly cheesesteaks, and from-scratch biscuits and gravy; and a Vegas bar that serves the best Stromboli Guy has ever had.
