You always hear like "that's not real tacos/burritos. This is real tacos/burritos" "that's a ruined Americanized version" or anything like those. Its not only Mexican cuisine USA is influenced at. there's food like California Maki, NYC Pizza, Macaroni and Cheese, and more Americanized food. It's not even only USA influenced with other cuisines map sometimes the non-traditional version can taste better than the traditional ones i have to admit. So far, its the Mexicans i hear the most. I rarely hear the Japanese, Italians, Germans or any countries that influence other complain about those countries having their own version of their food.
