I dare say many Americans would not like "authentic" Mexican food. I however like variations of Mexican food, that are very tasty, like
--El Pollo Loco, and --Rubios.
El Pollo Loco started in Mexico in the mid 70s, and eventually expanded into the states. Now in CA, AZ, NV, UT, TX
EPL is very healthy and they have posted content in stores, since the Mexico ownership era. (Lindora's approved)
You will see plenty of "Mexicans" eating there. Good value for your money, too.
Both of these brands have excellent salsas, such as Pico De Gallo, chipotle etc.
I have had Tex Mex, and Arizona style but prefer Los Angeles style.
Some "authentic" sauces are lousy, btw. Too hot, no flavor.
