Oslo opera house was ready in 2008
The Opera did quickly become a favourite tourist attraction and has given the city a positive improvement, especially in the appearance of the area around the train station.
Very popular to walk up and down on the roof where you get a great view over the area and parts of Oslo.
On summer evenings you may find some outdoor entertainment by the Opera water front, with live music and TV-shows.
Here is also a great restaurant with a lovely outdoor seating,
it’s really nice with excellent service and food.
Prices for a three-course dining is about. 30-40 euros.
The wines are somewhat expensive, with prices from 40 euros up to 100 euros per bottle
But it’s also possible to just grab a coffee or beer here to enjoy the cozy spot.
