L'Avenue de Champagne is a famous street located in Épernay, the 'Capital of champagne', in the Champagne-Ardenne Région of France. Its name derives from the presence of many leading champagne producers such as Moët et Chandon, Mercier and De Castellane. Residents say that this avenue is the most expensive in the world, more so than the Champs-Élysées in Paris, because of the millions of bottles of champagne stored in the kilometres of chalk cellars beneath it.
