Fodor's Expert Review Gamle Rådhus

If you're in Oslo for just one night and want an authentic dining experience, head to the city's oldest restaurant—housed in Oslo's first town hall, a building that dates from 1641. It is known for its traditional fish and game dishes that take full advantage of the city's access to the best seasonal produce. An absolute must, if you're lucky enough to be visiting in December, is the house specialty, the lutefisk. Reserve well in advance for the julebord (pre-Christmas) season.
