Contrary to the other listing in here, it was sold to Taco Bell in 1984. The "taco dog" was actually called a "Taco on a bun". The last remaining location was in Pasadena and the name was changed to Pop'n'Taco. I know because I worked at the Alhambra,CA store for 5 yrs. and our district supervisor Mike VanSickle bought the store in Pasadena.
