The first Childs Restaurant was founded by Samuel and William Childs in New York City’s Financial District. They revolutionized dining by emphasizing cleanliness, efficiency, and affordability for the working class. Childs introduced innovations like white-tile interiors, waitresses, and the tray line cafeteria format. The chain quickly expanded, reaching 107 locations by 1925. The company's growth led to significant real estate investments, such as the Savoy-Plaza Hotel partnership. However, conflicts over William Childs' push for vegetarianism led to his ouster in 1929, marking a turning point for the company.
