The AA is Britain's oldest school of architecture, but anyone can take advangte of the great work going on there. You can catch really interesting public lectures and free exhibitions throughout the year. There are also occasional installations and event launches, a bijoux cafe and brilliant bookshop. A great place to hang out with the builders of the future.
Cordings situated in piccadilly is a renowned establishment for British Country clothing and tailoring - that can not only kit you out to shoot pheasant in the finest yellow ochre cords but for me offers a great selection of socks.
