I noticed my cannibal feasts were getting poor quality, even at 100%. It turns out they aren't getting any room bonus.
The ritual start screen displays the full 20% bonus. However, the room's impressiveness is checked at the very end of the cannibal feast. Since the feast generates a massive amount of bloody mess, by the time the feast was done my very impressive dining room was awful.
