Hiltl
This restaurant serves vegetarian food since 1898! Greatest selection of very good vegetarian cusine in switzerland! Try the salad buffet with over 40 dishes and the indian buffet too. Whenever I go to zurich I stop at hiltl. They also serve great fresh pressed juices.
The restaurant is always fully booked, pre reservation is necessary if you want to go at a certain time. If you come and leave early you get some discount. more
