Definitely stop by Ernesto koffie (right at the roundabout Walensebaan and Smisstraat), a cozy little food truck right by the ponds. There are also cozy seating areas provided at the food truck itself. Delicious coffee and wonderful pastries. Ideal for a refueling stop. Super friendly service. Open Wednesday to Sunday from 10:30
