This tiny place just north of the Watterson (across from K-mart) looks like a fast-food joint, but the vittles are about as authentic Mexican as you'll find in the Derby City. Crisp or soft tacos and burritos the size of paper-towel rolls feature a variety of fillings from crunchy carnitas (roast pork) or carne asada (tender beef with onions and green peppers) to beans, rice and avocadoes. $
