No Del Taco or Wienerschnitzel here. The former has tried twice, the most recent time in the last couple of years, and just hasn't been able to last. Wienerschnitzel left 30 years ago or so but they are elsewhere in Texas and may be in some of the outlying suburbs. I liked the hot dogs back when and usually stop for old times sake if II see one on the road.
I checked Taco Cabana out of San Antonio which labels itself fast-casual - no tamales. Taco Palenque, a very good Mexican fast food chain out of South Texas (only one here) - no tamales. Likewise a local taqueria 'chain' plus Taco Bueno (here and gone) and Taco John's (never here but I've heard good things) Nada.
But El Pollo Loco (out of Sinaloa by way of Los Angeles) has tamale offerings on the Seasonal Favorites menu.

I thought they had given up after a brief try at entering the market back in the 90s but there are a half dozen or so, including one within a reasonable distance from me. I've never had any of their food but will try to make it over before the Season is up.
Incidentally the entrepreneur who started El Pollo Loco and still owns the Mexican company is the same man who started Taco Palenque. This might be pretty decent. They even have a crispy tamale bowl; the only place I've ever seen fried tamales is a Salvadoran tamaleria. I'll report back if I'm successful.
