There are canteens, known as the university’s ‘mensas’, dotted all around the research campus, where you can eat quickly and cheaply. Students can obtain the Mensa stamp from the Secretary’s Office of the Austrian National Union of Students. The stamp entitles you to a discount on the daily menu.
There are also numerous restaurants and cafés on the campus and in the immediate vicinity of the uni, which sometimes offer good-value lunch menus and snacks. The menus cover everything, from traditional food, vegetarian and vegan to Asian dishes.
