mensaH is a Dashboard widget that hows the food menu of the all the mensa/cafeteria of the university of Hannover/Germany.
So it's only useful for people studying there or at least who are eating there.
Sadly, this otherwise excellent widget fails to inform one which of the comestibles on the menus are made with organic ingredients, which of the meat dishes use grass fed beef or whether or not any of the dining halls are fart free......all major and egregious oversights on the part of the developer.
