Hailing from Texas, most folks claim that all we know down there is Tex-Mex, and that El Charro's is Authentic! Well, even the Mexican waiter I had said it was mediocre... very nice guy BTW and he seemed to appreciate my ordering in Spanish.
Taco's were wet/watery/soggy. Chicken fajita meat was flavorless chewy chunks. Chips weren't good. Queso there is not like Tex-Mex ( creamy cheese, guacamole, sour cream, beef) but is rather like the stuff you stick on veggies. Even Velveta would be an improvement.
Texas rule of thumb, the more Mexican food costs, the worse it is... so far El Charro's meets that standard.
Pros: nice waiter
Cons: , soggy tacos
