Aker Brygge is the area along one arm of the Oslo Fjord, on the west side of the harbor. On its website it defines itself as the meeting point for shopping and eating out, for quality and contrasts. That means it offers quite a wide choice of locations with various purposes, but mainly all of them offer good quality products and top class ingredients.
I really like to walk along the shore in this area, and either stop at one of the many boats that have been reorganized as restaurants/bars or simply sit on one of the benches with an ice cream in my hand. The sea can offer a very relaxing sight there.
Another cool thing about this area is that it is connected with the wide space in front of the City Hall and every weekend (if not every day) you get the chance to catch street performers or a bunch of tents hosting various exhibitions. The best ones are International food fairs where I was able to taste a wide variety of foods from most of the continents. At the ‘sea’ end of Aker Brygge, you’ll find the newly built Astrup Fearnley ArtMuseum.
Plus this is the place from where you can catch boats and ferries. The area is constantly being rearranged and buildings are ‘upgraded’ or built from scratch, so keep an eye out for novelties at all times.
