Hiltl

"A leafy anomaly in a meat-and-potatoes city, the vegetarian Haus Hiltl restaurant dates back to 1898, when one Ambrosium Hiltl decided rösti potatoes and Spaetzle just weren't enough."

"Plan on eating early, or expect to wait in line for the impressive salad bar of 100 homemade dishes (you pay by the weight, per 100g, or about 3.5 ounces)." Full review

"The Hiltl is the world's oldest vegetarian restaurant, with a buffet offering more than 100 dishes. The spacious premises include a bar, shop - and night club!" Full review

"Hiltl is hailed as the world's first vegetarian restaurant, having served a la carte plates and a massive buffet (with over 100 dishes) to herbivores since 1898: but even meat-lovers will leave happy." Full review

"When it opened way back in 1898, Hiltl was Europe's first vegetarian restaurant; over a hundred years later, it remains Zurich's top vegetarian option, with daily changing seasonal menus" Full review
