We stopped here for the second or the third time on the way to/from San Antonio. First time we stumbled on it by accident, now we always watch the exits carefully so we don't miss it! The tamales are excellent. Reasonably priced, nice outside patio. I guess later in the evenings there is some live music and an outdoor bar, but we haven't experienced that. Just a tamale lunch.
If you have kids, the outdoor swing/slide company next door has a great demo play park -- don't miss it :)
