When I travel through France, I always try to have at least one Kir Royale. It is a fairly common drink, named after Canon Felix Kir, a former mayor of Dijon, who popularized the use of the local white burgundy wine with a splash of cassis, which became known simply as "Kir". With champagne, it is known as a Kir Royale.
