This image needs some correction for Norway. Only SubWay, MCD and BK are prevalent. Dominos have mainly places on Oslo, and a the rest are mainly in the larger cities. Starbucks 10. Most in downtown Oslo.
Think Pizza Hut pulled out of Norway years ago
It should have been a color gradient per capita. Starbucks has a very poor holding in Portugal because Portuguese people like good espressos, not dirty water.
Not completely, as they had some locations in airports, both Gardermoen and Værnes at least. Not sure when they closed, but I ate at both somewhere around 2018.
They disappeared before Covid hit and I swapped to a non-traveling job though.
