Ahhah!! Found it! El Torito's
I hated driving down there because one saw nothing but flat flat flat farmland and monotonous landscape, but once we got there, we loaded up on Ruby Reds, cajeta (goat's milk caramel), pottery, paper flowers, and vanilla...that was back before Mexican vanilla was banned.
I actually miss those days. We only went into Reynosa because my dad's godfather had a very good rapport with the locals and we knew we wouldn't have much trouble if he was along.
