Many tourists join the locals in the long queues at popular Brussels fritkots such as Frit Flagey and Maison Antoine.
"Before I came here, one of the only things I knew about Belgium was that they liked their fries, so I think they are pretty much there already," said Rachael Webb, a visitor from Ottawa, Canada, holding a cone of fries.
UNAFRI, the national association of fritkot owners, which started the drive, says the unpolished establishments are uniquely Belgian, combining the country's embrace of chaos with a dislike of corporate uniformity.
