Amazing place - cute, cozy and great food! The owner is really nice, and though he is really shy about his English - it's pretty good (for German standards). He has explaned all dishes to us and helped us choose.
Both starter and main course were really good, fresh and presented nicely on a plate.
The price was very low, in my opinion, we payed 37 for 2 people - we both had starter and main course, my friend had wine and I had dessert and tea.
The restaurant is quite small and there were not so many people, but atmosphere is very nice and makes you want to come back.

Friendly, light room, non-smokering facility.
I found the food possibilites for vegans quite small, but you can ask the crew for modifications for the meals. They should have more standard options for vegans though.
In the summer, one can sit outside in the backside garden.
