A nice little place, in the heart of the tourist area.
It's a little cafe inside a "Whole Foods"-like store (Reformhäuser are common across Germanic areas). All the food is vegetarian, and much of it appeared vegan. There's a little sitting area attached.
The daily offering is an array of six or so cold dishes (green salads, grain and lentil salads, pasta), all quite tasty and healthy. If you've had your share of bread and cheese, you'll find this place especially welcome. Friendly staff, and reasonably priced.
I didn't expect to find actual prepared food at the store, much less food that was tasty and felt healthy, so it was especially nice to find this place.Pros: taste + health, inexpensive, location (for visitors)
Cons: not fancy, limited selection, weak ambiance
