Pure Taqueria has several locations; I tried the Alpharetta site. The Virginia Highlands site is in an old gas station. This one, I suspect, isn't but is still very cute. It was hopping on Friday night. The mood is upscale casual, starting with the valet parking.
I started with a little salsa. It looked innocuous enough, sort of a rough puree. So I swigged a shot and got a very hot surprise. These people definitely know how to do hot---the salsa verde with my tacos was also very hot. The afterburn was very pleasant.
I went for the grilled mahi mahi tacos. The fish had a distinct but not overwhelming sense of the grill---just a touch of char without hiding the fish flavor---and was tender and juicy. It also came with avocado, some grilled vegetables, and the aforementioned salsa verde. The tortillas hadn't been made locally but they were pretty good.
