Hi,
Sorry about that - it took me a few years before I could PRONOUCE Akershus, much less spell it

!
That used to be one of my favorite restaurants. I haven't been back since they Princess'd it, but it's still a buffet, and I don't think there are sandwiches on the menu, even at lunch. I think you mean the Kringla bakery, which is in the same Norway location - they have a soup and sandwich special (I've copied this from the menus on All Ears):
Kringla Daily Chef's Selection - Your choice of open-faced sandwich with a cup of Jarlsberg and Leek cheese soup, accompanied by your choice of rice cream, veiled maiden or no sugar added chocolate mousse
I'm sure that this is available all day! You can look at all the menus on AllEars - here's the link:

Take care!
