on your tastes. A whole lot of little girls love the princesses, so that's why many do visit Akershus. But, I have also heard about people who come there just to enjoy the food and atmosphere, not the Princesses.
I for one would prefer Park Fare, not only because I love the British Disney characters, but also because they feature a buffet for breakfast, which is more wide-ranged. I am a picky eater, so eating at a restaurant that's simply menu-item based, I'm limited down to certain foods. With a buffet, it's not only more familar to me, but I also get a wider variety. That's good for some picky kids too. Not only that, but it's one of the character meals that has NO princesses! Plus, Mary Poppins is there! Who wouldn't want to meet her?
So that's why I think it really depends on your tastes. What food you like, the way it's served, and what characters show up.
