Costas Spiliadis is a chef and restaurateur, born in Patras, Greece, in 1947. He immigrated to New York in 1966 to study criminology at New York University. In 1971, he moved to Montreal, where he worked as a radio programmer for Radio Centre-Ville. Finding a lack of high-quality Greek restaurants in the area, Spiliadis decided to open Estiatorio Milos in December 1979 on Park Avenue.
