Behind its hulking, centuries-old walls, cosy, wood-beamed Kronborg serves up classic Danish fare. Head here for the impressive choice of lunchtime smørrebrød, appropriately served on Royal Copenhagen china. Favourites include the sweet, succulent Brantevik herring, marinated in sugar, vinegar and allspice and topped with fresh herbs. Toast to tradition with an akvavit or a craft brew from Copenhagen's own Nørrebro Bryghus.
