Sky Garden is a bar and restaurant complex on the top 3 floors of the 'Walkie-Talkie' - 20 Fenchurch Street in the City of London. This controversial 38-storey office block was designed by Uruguayan architect Rafael Vinoly - the footplate actually increases in size as you ascend the building. It cost £200million and was constructed between January 2009 and May 2014. Sky Garden, which has restricted, but free, public access, was opened in 2015. Here you can enjoy an expensive drink or a meal with some fabulous views over Britain's capital city. You need to book in advance via the website (see below).
