You might be on to something with the vegetarian thing. I too am pretty disappointed by the tex mex options, in North Austin at least. I live north, so do not get to all of the places in South Austin, of which there are many. ← Just noticed this on a site reviewing Maudie's, an Austin tex mex chain. Confirms your theory! "The only item that's a little out of the ordinary is the beans, which are 100% fat free and vegetarian."
