When we lived in San Antonio in the early 1960s, they had a chain called “Pig Stand” and then a number like 39 or whatever.
As I remember, the buildings were small and offered only counter seating, but they were very popular.
Does that chain still exist?
Sadly The Pig Stand closed last year after 100 years.
