"McDonald's is a fast food company founded in 1940 as a restaurant in San Bernardino, California, United States."

However, searching elsewhere: McDonald’s was founded in the year 1955, while Burger King came into existence or was founded in the year 1954.

And to add to the story: The oldest McDonald’s Red and White (opened in 1953) still operating today is in Downey, California.

How does a chain, founded in 1955 have the oldest restaurant, opened in 1953? ❓ But they were started in 1940?

And the best of all I saved for last.
