In Mexico, taco stands are commonly referred to as taquerías, because originally a taquería was typically a street vendor. However, many taquerías today are restaurants located in buildings. Taco stands may be located at roadsides and in areas where people gather, such as at outdoor mall areas. Taco stands are typically located outdoors, although the term is also used at times to refer to taco restaurants. Some taco stands are temporary operations, set-up for events such as fairs and festivals.
Meats used include beef (such as carne asada and cabeza), pork (such as al pastor), goat meat (such as tacos de birria), shrimp and fish, as used in fish tacos. Additional ingredients used include cheese, salsa, guacamole, sour cream, various vegetables such as onion and cilantro, and hot sauce, among others.
