Im glad someone asked this ?, I too have been wondering cause unlike most Im not a big Tex-Mex fan after living in Mexico for 6 months! Man we have no idea what real mexican food is, im glad I kept my ressie then!
Authentic, yes, but that doesn't make it good. My grandmother is Mexican and I do not do tex-mex at all. I've been there twice. The first time was barely OK. The second was not even edible.
