Just above the place de Jeu de Balle in the heart of the Marolles, this café is a local institution known for its set brunches. These are rib-sticking meals, with muesli, yogurt, eggs, croissants, and some combination of cheese and ham. It's a staunchly Flemish place; the staff doesn't appreciate orders in French (English is preferable). When the neighborhood had no running water, this is where residents would come to get hot water—hence the name. Before wandering down the street to the Vieux Marché (flea market), get a snack of tasty bread and cheese or an omelet here, washed down with a bowl of lait russe (milky coffee). Note that as of this writing, the building is up for sale, and there are dark clouds of uncertainty hanging over the future of this place.
