What was the name of the McDonald brothers’ original fast-service restaurant system?

The McDonald brothers’ original fast-service restaurant system was called the Speedee Service System.

Richard and Maurice McDonald developed the system in the late 1940s after reorganizing their San Bernardino, California, restaurant. It simplified the menu, standardized preparation, and assigned kitchen tasks so food could be produced quickly and consistently.

The name influenced early McDonald’s branding. Speedee, a chef-like mascot, visually represented the system and appeared before Ronald McDonald became the chain’s signature character.

The Speedee Service System is sometimes confused with the modern McDonald’s brand itself. It was not a later advertising slogan or a menu line; it was the operational model that helped make the restaurant attractive to franchisees and eventually shaped the chain’s identity.
