1 am: New York, United States
Head to the top of the Empire State Building. Its observation deck is open until 2 am – the ultimate place to survey the city that never sleeps.

Join the early-rising meat traders of the 140-year-old Smithfield Market – though you will have to wait until 6 am for the nearby Hope pub to open.
