The hotel I stayed at had both gluten-free crisp bread and regular bread, and I used toaster bags to make sure that there wasn't any cross contamination issues when using the toaster!
I mean, look at this leaning tower of hamburger!
Almost everyone in Norway speaks English, which means you'll have no trouble talking to the chefs and servers about the gluten-free diet. The waiter walked me through the buffet offerings, pointing out what was gluten-free and what wasn't which was really nice :).
How cool is this wine glass candle thing :)!
If you ever find yourself in Norway on the gluten-free diet, don't fret, because you'll be just fine!
