Tucked away in the charming, open-air Mercado San Agustin, this is where you'll find some of Tucson's most authentic Mexican flavors. You'll order at the counter before grabbing a table in the lively, tree-shaded courtyard, which often features live music in the evenings. The handmade tortillas are a must-try, serving as the perfect base for their tacos inspired by six different regions of Mexico.
