This is an old established restaurant in Oslo were a lot of people go to see and be seen. It costs quite a bit to dine here but in my opinion it's worth the dimes you spend. Service is good, many of the waiters/waitresses has been there for years and does not have this only as a hobby (as it can seem like in many other places). It can be rather crowded for lunch in the weekends before christmas so if you are a larger group book in advance (one or two month). It's not mutch room for strollers, so think about that before bringing small kids.
