Hot Shoppes was an iconic American restaurant chain founded in 1927 by J. Willard Marriott and Alice Marriott in Washington, D.C. Starting as a simple root beer stand, it grew into a pioneer of drive-in dining and regional comfort food, famous for its "Mighty Mo" hamburger. The chain's massive success laid the foundation for what would eventually become Marriott International, one of the world's largest hospitality companies.
