So as you can see, the taco isn’t an age-old cultural food, and it is fairly new, compared to some of the other Mexican foods dating back to Aztec times. The role of the “taquería” (taco shop) is also important to understand the history of the taco. For many years, taquerías were mostly for working class Mexicans. Many women migrants brought tacos to Mexico City to sell for income. These women eventually made Mexico City into the hub for tacos, with many different styles and kinds of tacos that people could sample.
