McDonald's

Though McDonald's has since become a multi-billion dollar (and burger) company, this Downey drive-in, the fast food chain's oldest surviving location, stands as a reminder of bygone days. The golden arch-pierced, wedge-shaped roof was devised as a standard for franchisees to follow. Most other similarly styled McDonald's were demolished to meet the corporation's modern design standards, but this Googie relic remains as it was one of the few franchised by the McDonald brothers themselves.
