It certainly wouldn't have been unusual for a young Beto O'Rourke (or any other Texan) to have tacos on his mind for any number of reasons, but "Taco Land" was the name of a punk bar in San Antonio. It was well known to Texas punks and their ilk and was immortalized by the Dead Milkmen in the late 80s by their song "Tacoland".
