A Tucson tradition for more than 90 years, El Charro serves up Mexican food in the traditional Sonoran fashion. For the most authentic experience, check out the original location near downtown, along North Court Avenue. It is in an old house, with an expansive patio and bar out back. USA Today named the chimichanga among the best plates in America. It is made with carne secada, beef dried on an outdoor rack. But longtime Tucson folks love the Charro-style beef taco, a ground-beef patty, rather than crumbled ground beef, cooked into a crispy shell.
