Before we went to London I booked us a few moment inside the Sky Garden. From this 160 meters high building you can get a great overview of downtown London. When entering the building you first need to go trough the security checks. After that, a very fast elevator will take you to the top of the 38 storey building. Inside the tower is a big garden with bars and restaurant. And of course; a big sky deck for where you can see the river Thames and London.
Tip: make sure you book your tickets on time! I booked mine 2 weeks before our trip early in the morning. Ticket slots are released on specific times during the morning.
Sky Garden is located on 20 Fenchurch Street.
