The views from the top of the sore thumb that is the Walkie Talkie are grand. Tickets are free but must be booked in advance. Much better than having to burn a Shard-shaped hole in my pocket for a glimpse of how flat London really is, and how drab its flats are. Still, it’s quite a sight and offers a perspective of the city you don’t see every day. While we were up there, a flight passed by overhead and cast a shadow that stretched the length of Tower Bridge to London Bridge. Whoa.
