On the 9th floor of the former Eaton’s department store in Montreal is an Art Deco masterpiece, Le 9ième, a restaurant patterned after the dining room on the ocean liner Île-de-France. Lady Eaton herself opened the place back in 1931.
Since the Eaton’s chain went bankrupt in 1999, the restaurant closed, but as a listed architectural heritage site it is preserved.
Unlike other cities, Montreal doesn’t have a lot of Art Deco buildings. There’s the Aldred Building at Place D’Armes, the Atwater Market, arguably Central Station, and a few Depression-era works projects, a few apartment buildings in Côte-des-Neiges near the Jewish General Hospital with streamline details, a few private residences and… that’s it. So Le 9e is a real gem.
I think they’ve occasionally shot movies there; there’s a 1998 NFB documentary, Les Dames du 9e Étage, about the contrast of the working-class waitresses and the society ladies who still took high tea there.
I went to lunch there once with friends before it closed; it was at that point, to be charitable, cafeteria food steamed to make it easy for people with dentures. But the place was gorgeous. (Check those clerestory windows!)
