21. Pup ‘N’ Taco
Pup ‘N’ Taco had a very diversified menu: You could get tacos, hamburgers, hot dogs, and pastrami sandwiches.
The first restaurant opened in 1965, and success came quickly after that: By 1973 there were 62 of them.
In 1984, Taco Bell bought 99 Pup ‘N’ Taco restaurants in California, but not three stores in Albuquerque, two of which went by the name “Pop ‘N’ Taco” (pictured). Those stores finally closed in the 2010s.
