The first drive-through restaurant was established in 1948 by Harry and Esther Snyder of the In-N-Out Burger chain.
America's first drive-thru restaurant, Red's Giant Hamburg, a down-home eatery on Route 66 in Springfield, Missouri, opened its doors in 1947.
The chain's founders, Harry and Esther, equipped the initial location in Baldwin Park, California, with a two-way speaker so that customers could place orders without the need for a carhop. They built a drive-up window to one of its locations in less than 5 years, but not all of their locations would get one. The first true drive-through restaurant was erected in 1948 by Harry and Esther Snyder of the In-N-Out Burger chain. It featured a two-way speaker system that Harry Snyder had created earlier that year. In the United States, drive-in restaurants had been phased out by the 1970s in favor of drive-through service.
