Let me preface my comments with the fact that I spent 25 years in San Antonio before moving back to Pittsburgh. Good Mexican food is plentiful and CHEAP!
I should have known better when I went to Casa Reyna because the place was deserted; the cook was Asian; and perhaps most importantly, when I asked for salsa or hot sauce, after a puzzled look, the waitress brought me a bottle of some red stuff that was crusted over at the top. I've never been to a "Mexican" restaurant that did not offer homemade salsa and hot sauce.
The food was mediocre and expensive. I left thinking that they wanted to ensure I never came back.
