We've eaten at Akershus for breakfast and dinner (many times)- the food was not good at either meals. So we are trying lunch on our next trip. I'm hoping it'll be better.
Anyways, we dine there because it's my daughter's favourite place to see the princesses.
But as someone mentioned, if you are picky, I would go for the breakfast. It's just the basic breakfast (scrambled eggs, bacon, sausage, potatoe casserole (which is okay) and cold bar with fruit, and pastries).
