I brought my sister to Stockholm for her 30th birthday and booked this place based on reviews. It did not disappoint - the food was spectacular and excellent value for money - you'd pay triple that in London for what we got! The waiting staff were all so friendly and thoughtful, they spoke perfect English and were able to have a bit of fun with us, even recommending somewhere to go for drinks afterwards.
The restaurant is a bit off the beaten track, but so worth it when you find it. We had the 5-course tasting menu and it was superb, the dishes just kept coming!
The only thing was that the wine was more expensive than I expected, pretty steep for a bottle, but turns out that's the norm for Sweden in general. So always be prepared for the alcohol to add a lot to your bill! Although the gin cocktails we had were superb, so splash out if you can.
Absolutely loved it, will definitely go again when next in Stockholm.
