"Opened in 1898, Hiltl is part of a historic culture of spas and sanatoriums in Europe that pioneered vegetarianism as a treatment for various ailments. At multiple locations throughout Switzerland, the chain employs a pay-by-weight system. Help yourself to any of the dishes in the dining room (which run the gamut of global vegetarian cuisine, from samosas to salads) then take it over to be weighed before digging in. The Zurich location is in the historical Altstadt district, so you can easily walk over after some morning or afternoon sightseeing." - N.A. Mansour
