The Olympia Diner was crafted by the Jerry O'Mahony Diner Company, of New Jersey, who was said to have produced 2,000 diners from 1917 to 1941. These roadside diners were primarily metal buildings, prefabricated in a factory, and trucked to the location. The Olympia, originally opened in Massachusetts,was brought to Newington, Ct in 1954. The three sections were set atop a waiting foundation and the terrazzo floor was  poured on site. It is known as the longest stainless steel diner in the country. The "OD" as the locals refer to it, has been owned by 3 families.  The Kritikos and Goulias families respectively for 10 years each, and the current owners, the Gavrilis family, since 1974.
