I don't recognize any of these places in NorTex, except maybe Pappasito's and Chuy's. Don't really know of any decent chains up here, I usually hit the local places and little taquerias, of which there are many. I go to the Pappasito's in DFW airport quite a bit and get the beef tacos, which are pretty good. Can't say I've ever been to one of their outside restaurants. I should, just haven't noticed where they are.
La Calle Doce is a great place, but there are only two that I know of, in south Dallas area.
There are some Uncle Julio's, but I haven't been in years. Don't recall it being anything out of the ordinary.
On the Border is pretty generic.
Taco Casa is at quite a few gas stations. It's actually pretty decent for fast food. Compared to Taco Bell and Bueno, their big tacos and burritos have a heavy load of meat and stuff. The other chains have very little meat, mostly bean and fillings.
