Many Oslo chefs have developed menus based on classic Norwegian recipes but with exciting variations, like Asian or Mediterranean cooking styles and ingredients. You may read about New Nordic cuisine on some menus. It combines seafood and game from Scandinavia with spices and sauces from any other country.
Spend at least one sunny summer afternoon harborside at Aker Brygge/Tjuvholmen eating in one of the many seafood restaurants and watching the world go by. Or buy steamed shrimp off the nearby docked fishing boats and plan a picnic on one of the islands in the Oslo fjord or Vigeland or another of the city's parks. Note that some restaurants close for a week around Easter, in July, and during the Christmas holiday season. Some restaurants are also closed on Sunday.
