I met a friend for lunch at Doña Cata - a very good family-run Mexican Taqueria that serves up fairly authentic Mexican taqueria food at very reasonable prices. Doña Cata's food tastes authentic, but milder in chili heat than food you would get at Mexican or US taquerias.
The taco fillings are all very good, though the selection is not as extensive as the taquerias in the US and Mexico: they had carnita, al pastor, longaniza, carne enchilada, and some others. They didn't have lengua (tongue) which is a very common item down south. The prices are very reasonable - tacos are $1.75 each.
They have an excellent selection of home-made salsas in various chili-heat levels - ten salsas to choose from. Examples include - tomate verde, arbol, cacahuate (peanut), mexicana (like pico de gallo), aguacate (avocado done like a thin guacamole), etc.
They have other dishes - torta (sandwiches) and various mains. They also have a selection of takeout (eg salsas) and bulk items sold per kilogram (eg barbacoa de borrego (lamb), al pastor, carnitas, longaniza, bisteck, etc.). And to top it off, you have a good selection of Mexican pop and horchata. Some of the sides - the rice and beans, for example - could have been much better executed.
The quality is very good - especially the tacos ... better than Taco Mexico Rico downtown - and the prices are inexpensive....I would come here more often if it wasn't so far out of my way.
