Sattva is a no fuzz, no ambience sort of place. Go there for a good vegatarian (or vegan) meal that's filling and warm. They're only open for lunch 11.30-3.30pm and there's only one dish each day. But, it's a bargain at 79 kr for sure.
Most people eat in silence and a lot of the regular guests have lunch on their own. Very unpretentious place. And, oh - they serve a killer "cheesecake" some days made from avocado, seeds and rasberry. Don't miss that one.
Cons: only one dish each day, only open for lunch, not all organic
