The restaurant (and surrounding area) has a very laid back artistic vibe that is very fun. As a tourist, I thought it had a different feel from the very central part of the city. Still, it was easy to get to and easy to find.
We tried three different fondue dishes in the yurt, each one was delicious and had its own unique flavour. It was quite cold outside but the yurt was perfectly cosy and we were able to relax and enjoy dinner. Once you have eaten fondue, you don't feel the cold again.
The place is friendly, relaxed and the food is good. I think the prices are about average for Zurich. The downside? I suspect that this goes for all fondue restaurants, but please make full use of the cloakroom and you may want to check that you are not wearing anything you'll want to wear the next day. The smell of cheese will haunt you.
