If I am not mistaken my wife and I spotted a Oaxcan style taqueria trailer on Richmond @ Mandell close to the Museum District. Does anyone know of any other around town if so, where are they, what is available, and the approximate price. I would love to find a tamale vendor who makes Oaxacan style tamales with black beans or mole amarillo (not the lady in Austin either). A good vendor making handmade tlayudas would also be great. We are limited to northern style Mexican here in Dallas, but on my trip to Oaxaca this past summer I learned that our guides husband spent some time in Houston with some relatives from Oaxaca so I know there is a population there.
