The kitchens are a polished, neat room with the house-elf, Ginger, often cleaning the dishes for Octavia herself. She is actually rather attached to the house-elf, but knows that in this household, at least, being friendly to house-elves is not done. There are a few cupboards with some food in it, and some tattered old recipe books that may have been passed down.
You may often find Octavia in the kitchens, pondering over what's for breakfast,lunch or dinner, although now she has taken to joining the rest for breakfast, so it is rarely in use in the early morning.
Ginger considers it her area, and takes badly to 'intrusion' by any other house-elf.
