Por Siempre Vegana Taquería is one of Mexico City's most celebrated fully vegan taco stands, operating in Roma Sur. The menu features plant-based pastor, chorizo, cecina, and seitan with chimichurri, all customizable at an extensive salsa bar with nopales and roasted onions. Tacos are priced affordably and the spot has become a go-to reference on every vegan guide to the city.
