Considered quintessentially American, diners emerged in the early 20th century, evolving from simple lunch cars to full-service eateries. They'd often open for extended hours and were positioned near highways. By the 1950s, they were fixtures of American life, offering affordable meals, hot coffee, and a place for locals to socialize. Known for their practical design and reliable service, diners became symbols of community and the golden age of roadside culture.
