The reason most travellers eat in El Reno is the onion-fried burger, which the town has been making since the Depression and now claims as its own. Three Choctaw Avenue diners — Sid's, Robert's, and Johnnie's — all do it well; the order is roughly the same at each, the rooms are all small and busy at lunchtime, and the question of which is best is debated locally without ever quite being settled.
