Papá Chano's is definitely the best Mexican restaurant I have been to. The service is exceptional and the food comes very quickly, and while you're waiting, their pico de gallo salsa is to die for!
My personal favorite is the chile rellenos: for under ten dollars you get two 4-5 in. long stuffed and breaded chiles, filled with rice, cheese, etc. On the side is Spanish rice, refried beans, and some lettuce, tomato, etc. with guacamole and sour cream.
If you're visiting in town, or live here, you've definitely got to try it.
