It isn't easy to find vegetarian food in Europe (as affirmed by this reporter), which is why Hiltl restaurant is unique. In an era when vegetarians were mocked as "grazers", it was a love story that gave birth to a vegetarian restaurant in Switzerland's Zurich in 1898. Ambrosius Hiltl, the owner married his head chef Martha Gneupel in 1904. Since then the Hiltl restaurant has been managed by the Hiltl family. On the 28th of June, 2012, Guinness Book of World Records verified that the Hiltl restaurant continues to be managed by the fourth generation of the Hiltl family. Rolf Hiltl, the great grandson of Ambrosius and Martha, manages the restaurant to date as NDTV found out on a recent visit to the property that is spread over five floors in Sihlstrasse, Zurich.
