The main block was built in 1947 as an L-shaped addition around an earlier Worcester Lunch Car Company diner.","why_significant":"The nomination calls it an early and important example of a built-on-site diner in Massachusetts. It combines the barrel roof and porcelain enamel of traditional Worcester lunch car diners with curved corners, center entry, L-shaped seating and glass block from 1940s diner types. It is also tied to the Contos family, who operated it from 1945 into the early 1980s and transformed it in 1947.","narrative":"Town Diner is a restaurant at 627 Mount Auburn Street in Watertown's Coolidge Square, built in 1947 around a smaller Worcester Lunch Car Company diner that was already on the site. That earlier diner was remodeled to serve as the kitchen. The new main block has a steel frame, porcelain enamel panels in cream and teal, a rounded hipped metal roof, rounded front corners and glass block windows at the corners. Inside, an L-shaped counter with a tiled apron and sixteen steel stools remains. Rooftop signs include a clock between the words TOWN DINER. The design blends the traditional barrel-roofed Massachusetts diner with sleeker 1940s forms. Louis Contos took over the business in 1945, and he and his son George enlarged it in 1947. The family ran it until the early 1980s. The property was listed for its architecture and its role in local commerce, as an example of an operator updating a diner and as a visual anchor of a neighborhood shopping district.","period_of_significance":"1947-1949","architect_builder":"DeLoria (architect, per building permits); N.
