Where is the oldest vegetarian restaurant in the world located?

"Haus Hiltl" Restaurant is a vegetarian restaurant in Switzerland. The restaurant holds the Guinness world record for being the oldest continuously open vegetarian restaurant in the world. The restaurant is in Sihlstrasse, Zurich.

In 1898, German tailor Ambrosius Hiltl moved to Zurich. In 1901, he became seriously ill with a bad case of rheumatism, which made it almost impossible for him to continue with his profession.

Two years later, in 1903, Switzerland’s only vegetarian restaurant, now called "Vegetarierheim", was in dire straits. Luckily, Ambrosius Hiltl, feeling better but now no longer working as a tailor, came to the rescue. Hiltl started working as the Managing Director and revamped and renewed the establishment to make it more appealing to the general public. Thanks to his intervention, the restaurant began to be more successful and, in 1904, after marrying local beauty Martha Gneupel, Ambrosius Hiltl took it over and renamed it "Haus Hiltl".

The menu offerings at Haus Hiltl are, of course, strictly vegetarian with many interesting vegan options as well. All dishes are prepared with quality ingredients, devotion, and attention to detail. The kitchen brigade focuses on local and regional produce and fresh, ripe fruits and vegetables, while all wine served in the restaurant is vegan.
