This restaurant is considered as a national monument as the inside is a huge piece of art. Definitely worth a look!
I regularly enjoy this place when I come to Nantes. The food is good, they serve great see food, oysters, etc... presented on a beautiful plateau de fruit de mer. Also good meat.
For desert, they have an amazing strawberry macaron ;-) (and the traditional profiteroles au chocolat, my favorite)
Service once in a while a bit slow, it depends on the affluence and time of the day, but last time was again very efficient.
Also they appear to serve a nice brunch, but I've never been able to test it as Nantes had loads of little cafes to take a simple cafe with a baguette.
