I wouldn't be heading back there for 2 days when I will be having my first day and induction working for the catering company behind the Championships. One of the other places I was dying to visit as soon as I got to London was a little café just off Oxford Street that specialise in Scandinavian Cusine. I found them after I got a huge craving for cloudberries (multe) which are native to Northern Scandinavia and wanted to know where to get my fix. Since then I have had them on facebook/Twitter and enjoyed their Nordic banter and being gagging to go visit them. Halfway up Great Titchfield Street it is quite difficult to miss their bright red front of shop but their punny blackboard outside will get you inside if not.
The cafe itself was a lot cosier and welcoming than I had even imagined with sofas at the front and tables at the back with the shop section. If you thought this was still pretty limited seating then not to worry as there was more downstairs. I arrived pretty late in the day so their full range of smørrebrød/smørbrød/smörgås was not there but what was there tickled my food presentation-fetish. I also couldn't resist some Kladdkaka which is a Swedish chocolate cake that has the consistency of brownie, if not a bit stickier, with a meringue crust. If that didn't sell it to you then maybe their nickname of "Crack Cake" will.
The cafe has a ridiculously friendly atmosphere in everything that they do, so much so you could probably fall asleep there and wake up to breakfast in bed, or them all snuggled up next to you. It's not just a café though, it is also a shop selling anything any homesick Scandi would want (mainly cheez doodles) and a great place for a non-native (such as myself) to wander around and feel like I'm on holiday.
