Anyone been? Tips would be appreciated.
We don't tip in Australia. And I don't think they do in Norway either.
If you tipped in Norway you'd need a 2nd and 3rd mortgage on your house just to go for a meal. Fantastic place (Oslo and Bergen are just fantastic cities) but MY GOD is it expensive!!!!
I haven't been to Oslo, but didn't find Bergen overly expensive. We stayed in an apartment so cooked at home, supermarket pricing was similar to that of Rome.
We used AirBNB all throughout Scandinavia, so were always staying in apartments. As a general rule of thumb, Finland < Sweden < Denmark < Norway in terms of least to most expensive.
For grocery shopping we (two of us) regularly dropped well over a hundred bucks catering for only a 2 - 3 day stay, and we certainly weren't buying anything particularly extravagant. So-called "luxury items" are definitely a killer in Scandy e.g:
6 or 7 bucks for a can of regulation beer (i.e. not boutique),
15+ bucks for a pint at a bar.
Around 7 - 8 bucks for a cup of coffee.
10+ bucks for a 500 gram pat of mincemeat.
Any time we ate out, a meal of standard pub grub (e.g. 2 x parmas or pizzas or similar, a couple of beers) the bill was equivalent to 100+ bucks.
On the positive side, fruit & veg wasn't all that expensive (especially berries which were cheap & good!)
