Very nice theatre!
Good place for cultural performances of any kind really with a huge stage, lobby, bars etc.
Its one of the best theatres in Oslo. They have good restaurants, i personally recommend "burger bar"
The service there was great, and the show that I went to (Ready Player 3) equally so
Was here during Les Misérables, great show and seats.
Var på Singing in the rain. Bra forestilling.
Best musical theater in Oslo
Good seats, great shows, you can also buy varieties of beverage (alcoholic and non) that you can take with you in to see the show. The only negative I have to say about this venue is thay it is mandatory to leave your coats/jackets at the check-in, and that the bathroom queue during breaks is ridiculously long.
It's the old Opera house and balle
A very nice theatre ("People's theatre"), used to be the opera in Oslo until the new one opened in 2008. Good seats with a good view from everywhere. You can preorder drinks for the intermission as well.
