The restaurant is a macrobiotic "club", hence you need to be a member (5 euro yearly membership that you can pay when you first go there). The food is fully vegan, although the macrobiotic philosophy admits rarely fish they don't cook it and don't use milk cheese or butter either - which are not allowed. You'll be asked to switch off cell phones by very friendly staff. Now, food... They are very "radical" in they priciples, in the sense that they don't use virtually any salt, or sugar, and they overcook food on purpose, to make them more digestible. It's an experience, but if you're open minded and once you get in the mood is nice. The price is ridicolous (with less than 10 euro you can eat a lot. They are also a shop of organic food. They close very early both on lunch and dinner.
Cons: maybe too integralist
