Very nice restaurant, very lively and from my point of view very french, bistro-style, no fancy stuff. Not many tourists there. The food is basque, if i remember correctly, with a great selection of cheese and sausages and excellent desserts.
i cannot really remmember the prizes, but i did not think it was expensive for eating out in paris.
Favorite Dish just order a mixed dish of ... suasages,
and try the basque cake.
