Marty Restaurant on ave. des Gobelins, Paris by Beausoleil Star this if you like it!
Family-owned since 1930, everything is made on the spot. It is a tiny bit more expensive than some other places but truly worth every penny. The restaurant is beautiful; the staff excellent and the food beyond reproach. Even better, they are open every day except Sunday evening. It's kind of an art-deco, jazz-themed restaurant.
