Four Kegs Sports Pub (Las Vegas, NV), Hullabaloo Diner (Wellborn, TX), Pizza Palace (Knoxville, TN) This week Guy sets out to find great Italian food in places that you would never expect: Pasta and meat sauce at a Tennessee drive-in; Italian sausage and peppers in a diner in Texas; and a Las Vegas bar that serves the best Stromboli that Guy has ever had.
