Given the rather glowing reviews about the kouing amann, we made the trip to buy some. In conclusion, it was the worst of all the ones we ate during our stay! A thin layer of pastry, topped with a layer of sugar mixed with butter - that's not kouing amann! The mixture was not very tasty, a big disappointment, and we don't recommend it at all.
Very good Breton raspberry and buckwheat cake, soft. I discovered this little shop during our stay in Brittany in June, and since then, every time I stay, it's a treat to return.
