Not much information regarding a menu can be found for the small and modern wine bar in the 11th, however, many posts and photos describe small plates that are both vegetarian and pescatarian friendly, and Conde Nast lists Le Dauphin as one of the best restaurants in Paris. The marble interior sets it apart from many of the other old France style bistros and as the sister wine bar to the famed Le Chateaubriand next door it may be worth a stop! We find when we travel that wine bars are often great options for dining, even if you are not one to enjoy wine – the menus are usually easily navigable for vegetarians and pescatarians.
