Named after the Belgian capital’s favourite little urinating rascal, this fast food frites shack on the Damrak has become an Amsterdam institution. Order your deep-fried potatoes in three sizes for €2.50, €3.50 and €4.50 and one of 16 sauces is included in the price from traditional mayonnaise or ketchup to an Indonesian peanut satay condiment. Other Dutch snacks like frikandel and kroket can also be had.
