Based on the Tripadvisor reviews I ended up having diner in De Mosselbeurs. I didn’t go for the obvious choice: the mussels, but decided to go for one of the suggestions: turbot fillet with arugula and lemon puree. The fish was fresh and the combination with the arugula and lemon puree was absolutely fabulous. Loved the dried tomatoes and capers. Service was very friendly. And I loved the atmosphere of the place with beautiful black and white tiles and a spiraling stair case in the middle of the room. For desert I enjoyed me some crème brûlée with orange and lemon zest which was delicious. In total my meal costed 42 euro, which is a little bit on the pricey side, I guess.
