I generally judge the worth of a restaurant by the quality of their Carne Guisada. In my opinion there are few things better than great Carne Guisada tacos. I think the best place in Austin that I have tried so far, and I've tried many in my 40 years here, is Rancho Grande at Anderson Lane and Lamar. I can't vouch for their other offerings since this is the only thing I order here, after all you don't go to the Louvre and skip seeing the Mona Lisa. Try it on Corn tortillas. Please let me know who you think makes the very best Carne Guisada in Austin and I'll give it a try.
