I can only say that you need to go to this place if you haven't.
It isn't cheap obviously, but what you pay for is far inferior to the quality of the service, and the food.
There isn't one thing that I can insist you try, instead I would suggest that you visit this place regularly, budget allowing, and slowly go through everything they have on their menu.
I would be very surprised if you come out disliking anything.
I simply love this place!
