This pop-up restaurant is only open when the weather is nice enough for it, as it is out in the open with no roof, right next to the Maas river. It's worth going the extra mile for this restaurant, located on one of the islands in the Maas. The ambiance is very relaxed and informal. We started with the fish cookies, and had fish and shrimp (from la plancha, of course) with sides of grilled veggies and tortilla with sweet potatoe. Their menu is based on what they get that day from the fish store. Everything is prepared on the plancha. Finished with a moist chocolate brownie. All of our dishes were very nice. Minor point: they're not allowed to serve tab water. Also, it was sometimes hard to get the attention of the staff. Go here with a relaxed attitude though and order your drinks early: having to wait in the sun with a bottle of wine is not a problem as we see it. Extra points for the original wine coolers! Oh, and as they only serve fish, don't go here if you don't like that, though you can just do drinks as well.
