A large Bic Mac meal with plain fries and soda is 123 NOK or $12.91, and a large double Quarter pounder menu is 168 NOK or $17.63.

It's actually relatively cheap right now, I expect a price hike soon given how much grocery prices have increased.

Scandinavian countries have very specific alcohol policies, though, very restrictionist, and the tax is part of this.

This is not just question of "more expensive country, more expensive stuff". Switzerland or Luxembourg are quite expensive, but you will buy affordable and good Italian/Spanish/French wine there, because these countries don't impose anywhere near as much taxation on wine.
