If you need a quick bite to to eat in Tucson, a Sonoran hot dog is a pretty good way to go. Coming west into south Tucson on I10, we took a quick detour north to check out Papa Locos.
Papa Locos lives in a little side addition next to a Valero gas station's convenience store. There are a variety of items on their menu, but the Sonoran hot dog was our focus.
Sonoran hot dogs (named after the Mexican State where they originated) are Tucson's version of the bacon-wrapped hot dog. To me, the primary factors that differentiate the Sonoran dog from its cousins are the addition of pinto beans and jalapeño sauce and the distinctive bun (which has the texture of a standard hot dog bun, but is shaped more like a bolillo).
Probably the most well-known place for Sonoran dogs in Tucson is El Guero Canelo, but I found Papa Locos' version to be superior in pretty much every way. The meat, beans and chile sauce each have their own intense flavor, and the combination is fantastic.
Papa Locos' Sonoran dogs go for $2.99 a pop. One each wasn't quite enough for lunch, so Sherry and I split a caramelo (a kind of mini-quesadilla) to pad out the meal.
