The Fosters story begins in 1946 when George Foster opened the first Fosters Freeze in Inglewood, California. He introduced the soft serve cone and a line of soft serve desserts.The unique product became so popular that he opened a chain of restaurants. As California grew, so did the Fosters concept. Made-to-order hamburgers, fries and other food items were added to the menu. Fosters Freeze truly could be described as Caifornia's first fast-food chain.
