Expensive, even by Norwegian standards with very mediocre food. Just to add to the underwhelming experience is the comedic levels of customer service. One example we witnessed was a waitress arguing with a couple after delivering them the wrong two dishes. She told them they were "wrong" which made our whole shared Sami room chuckle with mirth.
In fairness there does appear to be a total lack of customer service in the far north of Norway. In our experience it ended after Tromso. No training was evident, so they're just young people doing the bare minimum.
There's little choice in Karasjok, so if you find yourself here for a night, you have my commiserations and best wishes.
