Empellon Taqueria has been at the corner of West 4th and West 10th since 2011, and is still going strong.  We love having it in the neighborhood.  While so many restaurants either close or just become stale, Empellon has been consistently wonderful.  We love the spicy cucumber Margarita, and the tacos are more imaginative and better executed than what is typical.  They are not afraid to use organ meats (head cheese, sweetbreads, pork tongue) which we adore, and the service is always  faultless.  Ordering tip:  Ask for corn tortillas, they are more flavorful than the flour ones, and more authentically Mexican.
