As the world's largest hot dog chain since 1961, Wienerschnitzel at 6949 University Avenue in La Mesa anchors the University and 70th Street intersection with a drive-through-focused format. The proprietary chili recipe — a closely held formula owned by the Galardi Group — tops the Chili Dog, Chili Cheese Dog, and Chili Cheese Fries, a signature condiment program that occupies a different fast-food niche than the wood-fired Neapolitan pies at Surf Rider Pizza on La Mesa Boulevard. The chain operates more than 350 franchise locations, predominantly in California, Arizona, and Texas. This University Avenue outpost also runs the Tastee-Freez soft-serve program, producing dipped cones, sundaes, and shakes from a dedicated frozen-dessert station separate from the hot dog grill line — a dual-concept setup near the same Lake Murray Boulevard corridor where Anthony's Fish Grotto has served fried and grilled seafood platters since its founding near Lake Murray. The Angus beef dog line uses 100-percent beef franks grilled to order, available in Chicago, Kraut, and Jalapeño configurations alongside the standard mustard-and-relish build.
