We had dinner there in July and really enjoyed it. My three kids liked their pizza and pasta (true, not very Norwegian!), and DH liked his pasta with chicken. My salmon was horribly overcooked, but the potatoes with it were really good. Dessert was among the best we had during our entire trip, so good that we got seconds. The cold buffet was actually pretty good, too, with both basic things (bread, salad) and more adventurous choices.
Our princesses were wonderful. We saw Jasmine, Alice, Belle, Aurora, and Ariel (at dinner she's in the lobby only and poses for a photo with you when you arrive--the others circulate). Jasmine was very funny and teased my boys. DD4 got a nice kiss on the cheek from Aurora who was the absolute sweetest princess; that kiss (and the lipstick left there) made the entire meal worth it. I'd go there again, and we probably will on our next trip.
Have a good time. Your daughter is the perfect age for it.
