Back after a 3-days "city break" in Oslo. It was ok, I guess. Smooth experience: everyone will speak English and nobody will ever judge you from appearances (they kept trying to talk to us in Norwegian first). Lots of smiles, lots of new buildings, lots of money (it's freakingly expensive, even for people coming from "rip-off Britain"), lots of tech, lots of water, lots of people trying to make the world a better place... We packed quite a few activities thanks to the Oslo Pass, which you certainly want to buy if you are in town for one or two days; it looks expensive at first, but check the museum entrance fees and you'll see that it's extremely easy to break even in a couple of hours, plus it gives you free travel on all the (ubiquitous, clean and well-run) public transport.
To be honest though, I left with an "underwhelming" feeling that there was nothing to discover, nothing that wasn't perfectly organized, nothing terribly unique apart from the unique efficiency. Even bakeries all looked like classy joints straight out of the IKEA catalogue. Also, I expected more "Nordic specificity" but the city looks astonishingly like your average central-European town (plus the fantastic fjord). It looks like a very nice city to live in, but not the most appealing to tourists. If I ever go back to Norway, I'll probably skip Oslo and go straight to the northern fjords to enjoy the wilderness, which is the best thing in the country (as the fantastic panoramic movie at the Maritime Museum clearly demonstrates).
