Whenever possible I visit the "Veg out" for lunch. It is a small place with only a few tabels (in the summer there are some more stand tables outside in front of the restaurant). The meals are changing on weekly basis with some permanent meals. The staff is very friendly and the "chief cook" always tries to accommodate to your special requests. They also servce some vegan meals. Highly recommended place.
Cons: only a few (stand) tables, quite full at noon
