I came to this small town on a day-tour and this was one of the limited options available. We talked the the restaurant staff and they even confirmed with the kitchen which options were gluten-free and safe. Unfortunately I tested both options they recommended with my gluten sensor and they both came back with gluten found. So if you come to Giethoorn, I would recommend packing your own food. I did find another option nearby but that one was closed :(
— Not at all
— No gluten-free information on the menu
— Not Much/None
