Mexican Bakery- aside from La Mexicana on 1st
Mi Tierra isn't the best panadería in San Antonio, but it would certainly be the crème de la crème here. To date, I've tried Austin's La Mexicana, La Victoria, La Reyna, Joe's Bakery, and El Milagro, plus a few others. In my opinion, these bakeries are neither really good nor significantly above-average. They do provide a semblance of what I'm looking for, but they don't deliver on the deliciousness. (I might say the same of several well-known non-Mexican bakeries in town.)
This Spanish-language article mentions a new place (to me, at least) called Panadería El Sur at 9616 N. Lamar:
Given how mediocre the other options are, trying something new might be your best bet. If you do check out El Sur, I hope you'll report back.
