It is not prissy at all, we took our 3 boys there last year for dinner and it was wonderful. We hung out in the lobby while waiting for our table and we also spent some time with Fairy Godmother. The characters were amazing. I'm a little bias of course because our youngest was afraid of characters but as soon as he saw Prince Charming and Cinderella he went straight to them. The strawberry soup is a must.
To the OP, we went to Akershus for dinner and were disappointed in the quality of food and lack of character interaction. This was our favorite place to eat but sadly we will not be returning. However you can see several princesses. We saw Ariel, Belle, Jasmine, Cinderella, and Aurora.
The characters at 1900 were Cinderella, Prince Charming, Fairy Godmother, Perla, and Suzy.
