Le Procope opened in 1686, and has been in continous operation ever since. Why not take a walk along Rue de l’Ancienne Comédie, in Paris‘ 6th arrondissement, and have a cup of coffee where so many others have done for hundreds of years?
Or perhaps, A la Petite Chaise, which can be found in Rue de Grenelle (6th/7th arrondissement). This café opened its doors in 1680, and has served coffee, wine, and food to the great and the good for the past three centuries.
