Casey’s Diner, at 36 South Avenue in Natick, Massachusetts, is a rare 1922 Worcester model. Like many early diner owners, Fred Casey began as a food cart salesman. He purchased this ten-stool diner in 1927 and originally located it on Washington Street. It moved to its current location in 1977. The Casey family has owned this diner for generations. It is possibly the oldest continually operating diner the United States, and was added to the National Register of Historic Places in 1999.
