Our canteen (Mensa) is an institution for itself. One word you must definetely know in german is our very own verb "mensen" which basically means "going to the mensa".
A very normal question of Göttingen students could be "Hast du Lust auf mensen?" (Are you in the mood for "going to the mensa"?)

We have four different Mensen (Plural for Mensa) - Zentralmensa, Mensa am Turm, Nordmensa and Mensa Italia
Besides fish, meat, pasta, salads and desserts they all offer vegetarian and vegan dishes.
