We had breakfast at Akershus - the food was very good. There was a cold buffet of patries, cheeses, fruits and smoked salmon (this is Norway!). They brought the hot food (eggs, bacon, sausage, potatoes) to your table, family-style. You could ask for more of whatever you wanted.
One princess greets you as you enter and you have your picture taken with her (often, this is Belle). 4 other princesses will circulate through the restaurant as you eat, visiting at each table. They will stop and chat, hug, pose for pictures, sign autographs. It's a very relaxed way to meet the princesses. We loved it and are going back next time!
