Which McDonald’s restaurant in California is the oldest surviving location still operating?

The Downey McDonald’s is the oldest surviving McDonald’s location still operating.

The restaurant opened in Downey, California, in 1953 and retains the distinctive early “Golden Arches” design associated with the McDonald brothers’ original restaurant architecture. It is sometimes called the oldest operating McDonald’s, although the wording matters: an earlier restaurant existed in San Bernardino, but it no longer operates as a regular McDonald’s location.

The Downey building preserves an important stage in McDonald’s visual history. Its architecture used the large roadside arches as a strong commercial sign, before later branding increasingly emphasized the standalone Golden Arches symbol.

Another common mix-up involves Des Plaines, Illinois, which was the location of an early McDonald’s museum and reconstruction, not the oldest surviving operating restaurant. Downey’s survival makes it especially valuable for understanding the chain’s mid-century branding and restaurant design.
