What four-word service standard became a longtime McDonald’s operating motto?

McDonald’s longtime operating motto was “Quality, Service, Cleanliness, Value.”

The phrase summarized the standards McDonald’s expected restaurants to deliver consistently. It linked product quality with quick and courteous service, clean premises, and prices customers viewed as good value.

The motto became associated with the company’s postwar expansion and its effort to make the same restaurant experience recognizable across locations. It was especially important as franchising spread the brand beyond its original California restaurants.

The wording is sometimes confused with McDonald’s later advertising slogans, such as “You Deserve a Break Today” and “I’m lovin’ it.” Those were customer-facing campaign lines, while “Quality, Service, Cleanliness, Value” described the operating principles behind the restaurants.
