text: Although google spits out "triclinaria," I suggest "refectorium" is better. I believe that was the term for the communal dinning room in a Roman Catholic monastery or convent or religious house right up to modern times. And in more recent times, meals in the refectorium were buffet style--"pick your own." 
  
  Although I haven't looked it up, I understand "triclinaria" more as the dinning room of a ancient roman home, a place where one ate reclined on couches, with slaves as servers. Not the right image, is it?
