I am looking for suggestions on really authentic mexican restaurants in the Twin Cities. For years I have sworn by the food at Pancho Villa on Eat Street, however more recently I have noticed quite a few "not so authentic items", like the Caldo de Pollo (chicken soup), which is served with more of an Asian flare. I do love the tacos, the pozole, and the ceviche, but am interested in hearing other ideas as there are just too many Mexican restaurants to choose from in this area. (Excluding all the eateries in El Mercado Central, as I do frequent there quite often). Suggestions?
