El Caprichoso, the popular Phoenix hot dog stand where service is fast and courteous, and the Sonoran dogs are perfection. The split-top bun is always fluffy, the hot dog nicely charred and juicy, the beans nicely seasoned, and the various toppings — pico, a dusting of salty cheese, and a squiggle of mayonnaise — are carefully composed and balanced. The El Caprichoso Sonoran dog, enjoyed on a picnic table with a curbside view of the streets of Phoenix, is one of best dinners in town.
