Eat french fries. These are a Belgian invention. Stands (friterie in French or frituur in Flemish) serve them in large cones, with a selection of condiments that go far beyond banal ketchup. Another favorite snack is the famous Belgian waffle (gaufres in French, waffels in Flemish), which you can buy at stands and in some city bakeries. Waffles are considered an afternoon snack here, though. See our Belgium coverage.
