Mensa is
Latin and means "
Table" (from
mdn's write-up which has since been deleted). It is also what they call the large
food halls in a lot of (if not all) universities in
Germany that provide food for
inhabitants of said universities. Their prices are lower than those of the average eating establishments, and therefore (some people argue), so is the
quality of their
food.
The Mensas in Germany are run by the Studentenwerk.
