The First McDonald’s and the World’s Oldest Operating McDonald’s – Two Iconic Fast Food Stops in California

When you think of America, hamburgers and fast food are probably among the first things that come to mind. But did you know that McDonald’s history began in California — and that you can still visit the very first location and even eat at the oldest McDonald’s still in operation today?

San Bernardino – Where It All Began

In 1940, brothers Richard and Maurice McDonald opened their drive-in restaurant, McDonald’s Bar-B-Q, in San Bernardino. Back then, it was just a typical drive-in with carhops serving customers in their cars.

The big breakthrough came in 1948, when they introduced the Speedee Service System — a revolutionary fast-service model that transformed the restaurant industry. They focused on just three best-selling items: hamburgers, fries, and shakes.

The original building was unfortunately demolished in 1970, but today the Route 66 McDonald’s Museum stands on the same site. Here, you can take a real trip back in time: vintage menus, old ads, toys, and the iconic Speedee mascot tell the story of how a small-town idea grew into the world’s most famous fast-food chain.

Tip: If you’re road-tripping along Route 66, this museum is a must-see stop!

Downey – The Oldest Operating McDonald’s in the World

If you want to combine history with a meal, head to Downey, California!

Here, in 1953, the third McDonald’s restaurant opened — and it’s been serving customers ever since. This was the first franchise-run location, not owned by the McDonald brothers themselves.

It still preserves its 1950s charm: giant golden arches, a neon Speedee sign, and a small display of historical items inside. Walking in feels like stepping out of a black-and-white photo — only here, the burger is fresh and hot.

Tip: If you’re visiting Los Angeles, it’s only about a 20–25 minute drive. Go in the late afternoon when the neon lights come on — your photos will be perfect
