Majestic views of London. The place is free to go but you need to book weeks in advance. Views from London eye are a tad better due to its location on the Thames. But then, the lookout costs you nothing. They also have a strict control on number of people visiting so it doesn’t get much crowded. There is a toilet on the top floor in case you need to relieve yourself during the visit.

Can't believe this viewpoint is free and so easy to book. Thanks to it's layout it offers a unrestricted view of London's skyline. In my opinion its nicer than the recurrent sky garden, which you oversee from this place

The view from the 50th floor was fantastic and I was lucky that the weather was ideal enabling me to see over most of the city of London. The only restricted view was towards the North East. It was free to enter but you do have to book in advance so that numbers can be controlled. Thankyou to all the staff who did an excellent job and to the building owners for giving us the opportunity to enjoy the views.

Great place to see free views of London and much higher than the Sky Garden, as you can see from the window! You have to book, but we did it on the day and managed to get a slot at 4.30pm. Once up there you can stay as long as you like! It's much less crowded than the Sky Garden as not so well known yet, so there was no queuing to get in. We arrived early and went straight up. Well worth a visit.
