What is that rocket-shaped building?

I have been looking over pictures from a recent trip to London, and I
need help figuring out the name of one of the buildings. It is shaped
like a rocket ship, made of glass, and is not far from the Lloyd's of
London building. The picture of it is here

Also, if you could help me name some of the other buildings in the
picture, I would be very grateful.

Thank you,
