Biergarten, but then I don't want to eat while being constantly interrupted by princesses.

Just as a side note, if you chose to eat at Akershus and don't want the princesses to stop by your table, just let your server or the character attendant know. The princesses will be MORE than happy to skip your table and let you eat so they can pay more attention to the kiddies who ARE there to see them.
They do decorate Akershus for Christmas but that's about it. If you are looking for a place with a quiet atmosphere, this won't be it. Not that Biergarten is that quiet either.
