About Copenhagen
City overview
Copenhagen is a compact waterfront capital built around canals, bike lanes, and distinct neighborhoods. Start in Indre By for royal sights and shopping, cross to Christianshavn for canals and the Opera House, then head to Vesterbro or Nørrebro for restaurants and nightlife. Østerbro and Amager are better for parks, beaches, and quieter days.
Food & drink
Start with smørrebrød, a cardamom bun, and a pølsevogn hot dog; book New Nordic restaurants well ahead. Torvehallerne works for an easy lunch, Reffen for casual waterfront food, and Kødbyen or Nørrebro for dinner and bars.
