Sweden here. We have Starbucks but it is far far from popular, I think the main demographic is young women, Swedes don’t typically go for sweet/weak coffee like what they serve.

Dunkin’ has existed but I think it absolutely failed.

Pizza hut exists, but not in many locations, however they have been around a long time and I think they are moderately successful.

Burger King snd McDonalds thrive and have many locations. McDonalds struggle in the northern region where people swear by Max burgers instead.

Subway exist with moderate amounts of locations, have been for a long time. Probably doing okay.

Kfc is rare, but exists in the larger cities.

Dominos exists but I don’t know who is buying, in my opinion its sub par pizza at a high price point with poor service and long delivery times.
