I don't know where you are going, so I will just give you food tips:
Brunost (brown cheese) get a packet with pre sliced. Use it on bread with butter.
Gamalost (old cheese) same. Not everyones fave, but you will hardly get it anywhere else.
Jarlsberg, if you havent already had it.
Nugatti - Spread it on a sandwich
Grandiosa - Norwegian's idea of a frozen pizza.
Freia Melkesjokolade - Milk chocolate.
Vilti (formerly joika) racist canned food
Bache Gabrielsen - Norwegian cognac house
Juleøl - Xmas beer
Pinnekjøtt - West norwegian xmas dish
ribbe- east norwegian xmas dish
lutefisk - xmas dish nobody eats
Try different aquavits - Norway is the #1 aquavit country.
Oh, and try Kim's Mexican - #1 fave norwegian potato chips.
And buy Solo - Norway's fave orange soda.
Get Urge (0,5 l refrigerated sugar version) - Coca cola orange drink that never amounted to much in the US.
If you have the chance got to McDonalds and order a McFlurry just to see how pathetic it is without the plastic spoon.
And order a norwegian drink called Pjolter in a bar, see if they know how to make it. It is supposed to be Cognac and water.
Actually, while you are at it, try Olsen Driver - It is the norwegian Shirley Temple.
