A working 7th-century waterwheel powers a vintage flour mill that supplies its adjoining bakery with the spelt that is used to bake its 100% spelt loaves and vlaai (seasonal fruit pies). You can dine on-site at the cafe, and, if it's not busy, self-tour the mill and see how flour has been made for aeons.
Several other delightful restaurants dot the lane that links the mill to Onze Lieve Vrouwplein.
It also has a B&B apartment above.
