This is what a Parisian vegetarian restaurant looked like in 1954.  La Saladiere--even the name was chic and prescient--was designed by Mathieu Matzot, now memorialized in a book by Patrick Favardin. How typically French to glam up even if you were just eating what then passed for vegetarian menu options: boiled veggies and various lettuces.  Not surprisingly, the concept did not take hold with the French who were still under the thrall of boeuf bourguinon and the restaurant closed in a few years.
