Frank's is a trip by itself: American breakfasts and home-style Mexican food that's good, fast and cheap. And it feels like a '50s movie-set truck stop in, say, Buckeye. Habitués include the neighborhood working class, plus artists and writers priced out of the barrios. It's exactly what big spending guests from northwest Tucson resorts want to see when they ask where the locals go. The sign is a bonus photo op: "Elegant Dining Elsewhere."
