It's often said that the cleanliness of the toilets reflects the quality of the food.
A little effort could be made in that regard. Otherwise, the fish sauerkraut is simply the best I've ever eaten.
Very good crêpes, but a bit pricey. €12 for a complete crêpe and €16 for one with andouille sausage. The waitress was very professional despite the wait due to the crowds.
We had a wonderful time. The food was excellent. The service was impeccable, with very friendly and pleasant staff. We highly recommend this restaurant.
