We were there in June for dinner.
Both of my boys who are under three were given meals and drinks for no charge. I asked the waitress about three times and she kept telling me they could order what they wanted for free.
I know it goes against what you'd think, but this was true for us.
Akershus is considered a buffet/fixed price meal. All the entrees are the same price, and there is the cold buffet. On an earlier thread on this same topic, that is the reasoning someone applied and it seems that when we were there, Akershus followed that reasoning, too. I wasn't about to argue, as the price for my DD was $22 plus tax and tip.
