Forget the 25-pound-for-the-view Shard. Head for the Walkie-Talkie, officially known as 20 Fenchurch Street. Its top-floor Sky Garden offers breath-taking 360 degree views of London, for free. You may want to buy a coffee or/ and cake to celebrate the view at its Sky Pod bar. Access is airport-style and you have to produce an ID with your name (a credit card will do) before you are whizzed up to the 34th floor. There is a glass balcony and a garden featuring Mediterranean and South African plants. Staff say the best time to come is after 6pm Monday to Friday for the view and live jazz. The fifth-tallest building in the City, designed by Uruguayan architect Rafael Vinoly, it went through a bit of controversy. Still under construction in 2013, acting like mirror for the sun, it sent street-level temperatures up to 91 degrees Celcius melting a few cars parked nearby. Urban legend has it that City boys even came to fry eggs for a laugh. Hence its other nickname: the Fryscraper. Oh, and see if you can say Beschorneria Septentrionalis.
