This review is not as extensive as I would like as it is a month since we visited.
This restaurant is a little way from the palace but was conveniently en-route to our hotel (Novotel).
We first tried their menu, taking salad as one of the options rather than three crepes, both crepes were beautiful and tasty and the salad was large and varied. We drank Breton cidre which was also very good.
We revisited late at night, when I tried the Quiberon crepe. This was lovely and truly special. We were the last people in the restaurant but at no point did we feel rushed.
Whilst we were there we saw business people and families, all equally welcome it seemed, and I would recommend this to all.
The only thing I would watch out for is that it is closed during the afternoon. Otherwise we might have visited it even more over our four night stay.
