By the time we got there, we were pretty much just due to collapse in the hotel room! (This was predicted in advance.) Fortunately it was an incredibly nice hotel.
(Our final two nights in Iceland were at the Geo Hotel in Grindavik - both of these hotels are pretty much brand new - I was initially a bit horrified that I had rashly taken us from lovely cosmopolitan city to isolated country location, but really it is good to see something a bit different - we had an interesting walk around small town and harbor, and the nearby restaurant was surprisingly good - I think this is it - we ate three meals there as options in walking distance were limited.)
Food in Iceland in general was ridiculously good. I don't have links for everything (or even most things), but we had fantastic Thai food here, very decent random local pizza, tons of good fish (with and without chips), a beer at Nico's favorite place, steak lunch here with my friend J. and his two older kids after an episode of puffin watching and delicious cocktails in the lobby at our hotel.
The Golden Circle bus tour was a little overwhelming (the landscapes are amazing, but there are too many people - tourist infrastructure really isn't up to current volume); I loved the small zoo in Reykjavik and the Blue Lagoon also exceeded expectations.
(We had two very fancy meals in Iceland, food on New Nordic lines: one at the Lava Restaurant at the Blue Lagoon, the other at Haust in our hotel lobby. The regular-place food is so good, the fancy food is slightly wasted on me & B. - but it was genuinely exceptional, and I would especially single out lovely desserts. Not so photogenic - subtle rather than flashy - but utterly delicious: at Haust, a rhubarb victoria with almond sorbet, roasted almonds and arctic angelica syrup, and at Lava a poached pear with ginger sorbet, praline cake and elderflower syrup. Divine!)
Pictures below are piecemeal: the final ones are only a small fraction of what was on offer at the glorious Saga Lounge at the airport on the day we left!
