The world's largest fast food chain, McDonald's does business on an almost unimaginably massive scale: 1.7 million employees serve nearly 60 million customers daily at more than 34,000 locations in 119 countries, including plenty in St. Louis. Founded as a single drive-in in San Bernadino, California in 1940, the mega-corporation represented by the Golden Arches has become a worldwide icon of American efficiency. While the drive-thru's cornerstones remain burgers, French fries, and McNuggets, the menu is constantly evolving to suit a changing demographic; in recent years, Mickey D's has added healthier items like apple slices and an expanded salad menu, though the more indulgent offerings like the limited-run McRib seem to inspire the most loyalty. The chain's advertising is also taking aim at a younger, hipper demographic, with spots featuring young urbanites. The hard plastic tables and primary colors of yesteryear are now being replaced with cushy sofas and free-wifi to encourage people to linger after their McFlurries are history.
