I spent a day exploring the city on foot. I had a late check-in, so I decided to get some coffee and walk around the city. Oslo being the capital is the biggest city in Norway and is more commercialized, fast-paced, has a large number of immigrant population. You can instantly notice the difference if you have visited the other cities in Norway. Storgata street in downtown is a busy street comprising of restaurants, shopping malls, coffee shops, cathedral, and falafels stand. You can spend an entire day exploring the area that also has Vigeland's sculpture park, Viking ship museum and Akershus Fortress closeby.
