You need a good map and a good instinct of direction to find this place. So the words: a hidden treasure is in this case not a platitude but reality. Where do you find a real cook, a real cuisinier in the kitchen anymore? Most of the times it is hobby-cooking. But this is the real craftmanship or better said: cookmanship!
Go and sit and enjoy the taste of Marseille and try to discover the influence of Essaouira. We love the place. Only 3 month in town. Hope it will stay there forever.
