This drink was invented in 1938 by Walter Bergeron, the head bartender at the Monteleone Hotel in New Orleans, and is named after the French term for what we call "The French Quarter" ... le Vieux Carré ("Old Square"). The Monteleone is one of the Quarter's grand old hotels, and now features the marvelous Carousel Lounge, which is an actual revolving carousel -- you sit, and it revolves around the bartenders (just slowly enough so that you only get dizzy from drinks, not the ride).
