I hesitate to let everyone in on a little secret about some of the most tasty brkfst tacos around, but since itis off the beaten path only true afficionados will go. The name of the place is Villa Arcos on Navigation near the original Ninfa's (which is not owned by the Ninfa family and therefor isn't very good anymore)and brother let me tell you there are some tasty tacos to be had here. I generally get a "super" which is egg, beans, potatoes,cheese and either chorizo, sausage, or bacon. You can't go wrong with any of them. I also like to get a bacon, egg, and potato. The bacon is cut in huge chuncks not strips and is packed with flavor. There is no AC but it is covered.
I tried the barbacoa once and didn't care for it. The tamales and menudo are also good.
