We did it for dinner and before the new menu (even though it was only 2 weeks ago that we were there), but I will say that the food was absolutely wonderful, high-quality stuff--buffet, entrees, dessert, everything. My DH and I both had mustard-glazed salmon over baby red potatoes and orange and yellow roasted carrots. The kids around us were clearly having the time of their lives, so I assume the kids' menu was good too (they mostly were actually eating, too, which at character meals is an accomplishment).
We had Belle as the greeter, then Cinderella, Aurora, Snow White, and Ariel. As far as I can tell, that's a fairly regular combination of characters at all meals there. (We were hoping for Mulan or Jasmine, boo.)
So while I can't be all that much help, I would say that the food is definitely no reason to avoid Akershus, at least if you like seafood (there are non-seafood choices on the entree menu of course, but the buffet had a lot of seafood) and are willing to try different flavors. (Though mustard glazed salmon is hardly exotic

). We went pretty much just for the food, and we'd definitely go back.
