Kroc's restaurant not only served food but also presented a unique dining experience with carhops delivering meals to patrons in their vehicles. This model was instrumental in establishing fast food as a cultural phenomenon in America. The success of the Des Plaines location prompted Kroc to open more franchises, leading to the establishment of the McDonald's Corporation and revolutionizing the fast-food industry.
