Wow-Chinango! This place has the only decent plate of Puebla-style chilaquiles I've had since my time in Mexico in the '80s:sloppy, spicy, tangy, and filling. And that's not the only dish on the menu you've never heard of. They have mejorales, tlacoyos, and a few other creative ways of cooking and serving masa treats with their distinctive green sauce. I took the families of two of my sister here, and I still hear "Wow-chinango's" when they talk about Mesa.
The owner is very patient and friendly; he seems to enjoy explaining the dishes like any excellent waiter. We speak Spanish, so I am not sure how easy it would be to order in English only.
Prices are Filiberto-range. Atmosphere is basic, but I enjoyed studying the photographs of Huanchinango Township on the walls while our food was cooking.
