Café Månefisken has the most wonderful location in Oslo! During summer, the café is open every day (from September to April it is only open for events).
It is located in an old factory house right next to Akerselva (check the Akerselva article). The café has kept the old style from the factory that used to be here, and filled it with a bar, old furniture and a small stage. In the café they serve drinks, snacks and tapas dishes.
This café is situated right next to one of my favorite spots in Oslo – a bench where you can sit down and watch the waterfall of Akerselva and get into a peaceful mood (check the Møllefossen article). Also, from the outdoor tables on Månefisken you can enjoy the sound of the water and the view of the upper part of the waterfall.
This is a typical summer place, and so head over there to enjoy summer by the river!
