You Texans don't even know what Mexican food is!
It is NOT just food made by Mexicans! I've been around alot and I was raised on the Border. The best Mexican lunch can be had at Los Camperos in Brewster Washington and the best dinner can be had at either of the La Parilla Suiza in Tucson, Arizona. For breakfast, El Chef in Douglas, Arizona is best.
These recommendations assume you want to stay in good 'ol USA these days.
