This restaurant is walking distance from the central train station. typical macrobiotic fare, a bit austere and lacks romantic presentation, but one eats well, price reasonable. There is a little market that sells macrobiotic food/produce. Sometimes they have speakers such as organic farmer that comes in and give a talk. Cozy atmosphere.
Tourists beware, you now have to pay a membership fee of 5€ just to eat there even just once. if you go often, the membership is good for one year. Restaurants and Clubs have different fiscal status, and this is considered a club. thus the membership.
Cons: membership 5€, food tends to be bland, near trainstation-good for travellers.
