I haven't been there for years until recently, and the change there is crushing. It became cramped, insanely large buildings everywhere, Lloyds barely visible and tiny with the Cheesegrater next to it. It was an eye opening experience how much can change in a relatively (building age wise) small time.
EDIT: 2009 vs 2019 views of the LLoyd's building:
