Hmm, we don't have any Taco Bell's here in Sweden as far as I know. And not all US-based fast food places can make it here. For example Starbucks were trying to establish itself and do a heavy expansion. According to their webpage they only have 2 stores now, as they othere had to close due to not being profitable. Both remaining ones are in Stockholm.
And in the late 80s/early 90s McDonalds and Burger King had to close down in northern part of Sweden, as they got no customers (a local chain did some rather aggressive marketing, and there were rumours about the other being really bad quality etc). They have reestablished themselves there as far as I know.
Some chains have never even tried establishing themselves here (as far as I know). things like Wendy's Denny, Waffle house, Ihop...
One chain I do want here is the Irish chain Eddie Rocket's. Loved it when I worked in Ireland in 1996. Expensive (compared to Mcdonalds), oh yes, but well worth it.
