Several years ago I visited a still authentic soda shop with very fine cheesburgers and milkshakes made from that Bluebell's ice cream. It was outside San Antonio, right across from the San Marcos mall. I wanted to send a friend but can't remember the name and want to make sure it hasn't fallen from its former glory. Any folks there able to help out a Boston (by way of Nashville) hound with a fading memory? Any recs for GOOD Tex Mex within walking distance of Riverwalk because I'll pass those on too...Much obliged!
