The Kolonihagen brand is wildly successful in Oslo for its biodynamic and organic, ever-changing menus served up in a pleasantly rustic environment. A seven-course tasting menu is on offer every evening at the Frogner branch, with plenty of fish burgers and veggie options, and delicious sharing plates with smoked salmon and pickles. There's a leafy courtyard for al frescodining in summer. A slightly cheaper outpost has now opened in Grünerløkka.
