The number of Sonoran hot dog carts has multiplied in metro Phoenix over the years, but El Caprichoso is still the best. The beloved hot dog cart has been in operation for more than 20 years, so it's no surprise that its hot dog has been fine-tuned to near-perfection. The hot dog is squeezed onto a fluffy split-top roll that is beautifully griddle-charred. If you order it with all the toppings, it comes ladled with beans and pico, dusted with cheese, and decorated with a squiggle of mayonnaise. It's one of metro Phoenix's most quintessential and addictive meals.
