We moved to North Dallas 14 years ago. From Southern California. The day we moved in our neighbors from California and Arizona welcomed us. Then advised us that there is no good Mexican Food in Texas. They were basically correct. Tex-Mex and their liquid Cheese on everything. Gross.
And everything is Chicken......fried Chicken. Chicken Fried Steak, Chick Strips, Chicken this and chicken that. Thankfully, Pollo loco came to Texas. And IN N OUT, and there is a couple of authentic Mexican joints that have sprung up lately. Valerie’s Taco Shop from San Diego and Marianna’s Tacos in Frisco. Authentic enchilada sauce instead of liquid Cheese and chili dog sauce....(yuk) and they deep fry their own taco shells.
Other then that.....we like Texas.
For sure Tex-Mex and Mexican are distinct, but there are plenty of places in north Texas to get good food in both styles. You just have to know where.
