How to Have Fun in Oslo?

While travelling to a foreign country is always fun and exciting, many people are left wondering how to spend the time in between all the sightseeing and other tourist activities. Turning to locals for some input may not always be fruitful as they are the ones living there. So, the activities you may find to be interesting may be entirely uneventful for them. Some of them may rather spend time reading books or browsing the colourful casino Norge offers, rather than simply taking a walk around this amazing city.
