Los Achiotes is in colonia Naucalpan, which is pretty far from central CDMX. However, they make extremely good tacos de cochinita pibil, which are a specialty of the Yucatán region of Mexico. The owner, who is often there, is incredibly friendly, and because this place is away from the Condesa/Roma hub, you won’t find many tourists here. Go with their staple: tacos de cochinita pibil, which are slightly spicy and juicy without reaching the point where the sauce breaks the tortilla. Their tamarind agua is the perfect complement.
