Many blogs list this as the best crêperie in Paris with the most traditional and authentic Parisian crêpes and galettes. While I couldn’t find a menu, these blogs say there are vegetarian options, including egg and cheese, plain cheese, vegetable, and dessert crepes. You can’t leave Paris without having at least one crêpe!
