The chips are made with a special variety of potatoes originating from Belgium and northern France called "Bintje". The Belgian climate is perfect for growing them thanks to its nutrient-rich soil and humid climate.
The cooking method is also important - frites (as they are called in Belgium) must be fried using vegetable oil or beef fat "Blanc de bœuf". The temperature of the oil must remain below 175°C.

Belgium is the leading global exporter of frozen chips and the locals like to point out how they were not created in France but rather in Belgium - they are only called french fries for marketing reasons.
At the Expo, a portion of chips costs €4 and is served in cones just like in their country of origin. There is also a side "compartment" for the topping.
Next to the kiosk there is also a James Bint cardboard cutout - the name is a reference to James Bond and the "Bintje" variety - i.e. the official frites mascot at the Expo.
