El Charro Café occupies a historic stone-fronted house on Court Avenue in the heart of downtown, near the Presidio. It has been run by the same family for four generations. The food is classic Sonoran — carne seca (sun-dried beef cooked back to tenderness), chimichangas, enchiladas suizas — with margaritas to match.
It is touristy at lunchtime but the food is still genuine. Carne seca is the dish to order; the house aged it for decades on the rooftop. The original location is downtown but there are now several around Tucson.
