I've been to Taqueria del Sol in Decatur but never the one nearest my office. A Sonic Generator concert turned out to be the motivation I needed. The line extended outside the door but the service was quick and very friendly. And it's quite a value, too.
The surprise hit for me was the green chile encihilada. The chiles added just enough heat and a different texture to the cheese. (A sign by the register declared that the Hatch NM chiles will arrive soon.) The brisket taco, which I've also had in Decatur, was superb in all aspects: meat, sauce, tortilla. The El Pastor was fine but for some reason didn't inspire a strong reaction.
