If this is an authentic Mexican restaurant why they served burritos.and tortillas made from wheat flour.

There isnt many if at all actual authentic mexican resturants they are mostly if all Tex-Mex food and are modified to appease the american people , like the salsas which are traditionally spicy they tone it down alot , traditional and authentic you will get if you actually go down to Mexico but central and South mexico to be exact because even the northern states have addapted their dishes to appease the american travelers

Because many Americans associate wheat flour tortillas with Mexican cuisine. We always order cornmeal tortillas, they have them.
