Great food, great cocktails, great place to hang with locals. Not too expensive. Relaxed atmosphere, and really friendly staff. You can go there for just a snack, or a full dinner with wine. They also have a great selection of cocktails, mostly based on locally distilled Aquavit from Himkok.
Friendly atmosphere, a place you can talk to the table next to you.
If you have a hangover, go for the Bloody GRÅDI. A special version of Bloody Mary, with port wine. It is amazing.
