Zum guten Glück is for those of you with a sweet tooth. The cakes, waffles and crêpes are all delicious. It's often filled with kids in the afternoons.
This small café is for those with a sweet tooth. Cakes, waffles and crêpes are all delicious - and the atmosphere is deliciously sweet, too. Service is friendly and speedy, but do not come here if you can't bear with a bit of children's chatter, as the place is often filled with young and hip mothers and their offspring during the afternoon.
