One of the fastest meals to get your hands on in the park has to be fries and mayonnaise, and thankfully, it is also one of the most delicious! Of course, you can have it without the mayonnaise (heaven forbid!) and you can have it with ketchup instead. A few different counter service places in Efteling serve this wonderful meal, however my personal favourite place to get my hands on it is at Smulpaap, in Anton Pieck Square.
