My kids have both celiac disease, from the child menu the only choice was fries. They don't have a gf 'frikandel' or croquette, but they baked a burger separately. And I understood you can get gf bread.

I got here, hungry from hiking and asked if they had any gluten free options. 'Bread' was the reply. I ordered a broodje gezond and got two small buns nestled closely together to mimic a small baguette. On it was ham, cheese, lettuce, tomato, egg and sellery salad. Given the size of the buns, they were clearly gluten free. Very nice after a nice hike. No gut issues afterwards either!
