Which McDonald's restaurant in Downey, California, is the oldest surviving location?

The Downey McDonald's is the oldest surviving McDonald's location.

The restaurant in Downey, California, opened in 1953 and retains the distinctive Speedee-style architecture associated with McDonald's early expansion. Its design includes the original paired Golden Arches as architectural elements, making the building an important physical record of the brand before later restaurants adopted more standardized forms.

The McDonald brothers opened their first restaurant in San Bernardino in 1940, but that original site no longer operates as a McDonald's restaurant. The Downey location therefore holds the distinction of being the oldest surviving restaurant still operating under the McDonald's name.

The restaurant is also associated with the McDonald's history museum, which displays memorabilia and explains the company's early development. It is sometimes confused with the first McDonald's location or with the Des Plaines replica museum. Those sites have different historical claims, while Downey is the oldest surviving operating location.
