This is the traditional Dutch restaurant where I ate.
When Dutch expats or Dutch Canadians return to Holland, the ones I know seek out some old school Dutch food, especially if they have no family living in Holland. I realize many Dutch people living in the Netherlands might focus on ethnic food when dining out. That said , I am guessing in the rural and small town Netherlands, there would be more traditional Dutch restaurants.
We have a Dutch bar in TO that serves traditional Dutch foods. Bitterballen, snert, war fries, etc.
It’s hard to generalize about what the entire Dutch population eats.
