El Charro sits in a converted set of historic houses & buildings a block off Tucson's old town district—the same location where it began serving food in 1922.
We had lunch here, at a big old wooden table in a warmly decorated dining room. Ask to be seated inside, or else in the garden, if the weather's amenable. It's a bit cold and dim in the front of the restaurant.
I had an amazing vegetarian burrito, stuffed with roasted veggies, avocado and a green corn tamale. The others went for the excellent chimichangas, reputedly invented here (you can read the story on the menu). The special-brewed beer, an amber, was great, the salsa verde addictive, the decor a great talking point.
