Overall a nice restaurant that is reasonably priced for Stockholm and serves well cooked traditional Swedish dishes.
Myself and two friends turned up without a reservation and were seated straight away.
Venue is traditionally decorated - think Swedish beer hall and you pretty much get the idea.
Food was nice, my friends both had meatballs which were a hearty portion and very filling. I had the salmon which was also nice. Good value for what you get.
Atmosphere is warm and chatty. We were seated in the main hall, so lots of tables and talking which was nice and not overpowering.
Service was poor. We asked for table water from a waiter and were told no because he wasn't looking after our table. Food takes a long long time to turn up but is nice when it does so i suggest you order starter to fill the time.
During summer the restaurant does not take bookings - Swedes tend to eat around 7-7.30 so get in early to avoid a queue. That said you can have a drink outside while you wait so not the end of the world.
