Central London's City of Westminster is its political heart, while the City of London is where the capital's financial decisions happen. But be warned: Several paths across Hyde Park are pedestrian-only, and police often fine people who cycle on them. The City of London is a blend of old and new, with St Paul's Cathedral close to skyscrapers as well as Roman ruins. While north London has Hampstead Heath, south of the river is Richmond Park, which dwarfs its northern counterpart in size. There's also a branch in central London's Covent Garden — the flower-filled restaurant The Petersham — that has an sit-down deli and bar.
