I grew up all throughout the desert southwest of the United States. Everywhere you go it's Tex-Mex (Texas/Mexican) or some would say Cal-Mex (California/Mexican). Mexican food is my favorite kind of cuisine. With that being said, I would highly recommend eating at Dos Tacos. The food rocks. I've eaten there many times and I've never been disappointed.
They've done an excellent job with the atmosphere and the people there are super friendly.
By the way, I suggest the Quesadillas.
