Ralph’s Rock Diner, at 148 Grove Street in Worcester, Massachusetts, is a 1930 Worcester model, #660. Robert and Mamie Gilhooly originally opened this diner on Grove Street in Worchester’s Chadwick Square. After Gilhooly’s death in 1955, James and Mary Clingen purchased the diner. In 1979, ownership passed to Ralph Moberly, who moved the diner to its current location.
