First time I bumped into Sibiriens soppkök was a few years ago, during what that I think was my 8th move in Stockholm. This small informal restaurant is in Vasastan, precisely in an area called Sibirien (i.e. Siberia), an old nickname of the area from the 1800s (and here explained the first part of the name).
At Sibiriens they are specialized in soups (and here comes the explanation of the rest of the name!), cooked with simple and tasty ingredients. The menu changes from time to time, depending on the season and on the chef’s taste I guess, and they also serve tapas and other side dishes. A must for newcomers is the soup menu with three different soups to taste.
Sibiriens is a family run restaurant and you feel that, indeed. Is not only the quality and the care for meal preparation, it’s also (and mostly) the vibes around. Eating here really feels like being home having lunch together with the old uncle that lives far away and you visit from time to time.
