I never post anything here, but I felt it was my civic duty to inform the PDD community about Un Taco Mas by Rosie, a taco trailer in the parking lot of Old World Meats. Rosie is from San Antonio, Texas, and makes the best taco I have had in Duluth. I had one carne asada and one carne quisada. She made the flour tortillas fresh while I waited, the filling was amazing. She has a full breakfast menu as well, she is there from 7 a.m. to 6 p.m. every day. It is on the corner of Basswood Avenue and Central Entrance. The place is very much worth the visit.
