Americans have been going out to eat for as long as there's been a United States, but it wasn't until after World War II that fast-food and sit-down restaurant chains became part of the national fabric. Over the decades, tastes have changed and not all of our favorite restaurants have been able to keep pace. Howard Johnson's, with its iconic 28 ice cream varieties? Gone. The smiling Burger Chef and his yummy Top Chef burger? Vanished. These and other beloved chains may be gone from our roadsides, shopping malls, and suburbs, but they are definitely not forgotten. A few favorites have even made a comeback, such as one reboot that was just announced — Arthur Treacher's — though expect some changes, too.
