Most countries have their own snack you can buy in the street. In the Netherlands it is "het Patatje" or the "French fries" in english. You buy it in a paper cone with or without a sauce on top.
At the Unseen Photo Fair they sold biological fried "Patatjes".
Many couldn't resist a break with the snack and neither did we. I always like the traditional one "Patatje mayo" (with mayonnaise) yummy!
