So i'm going to be in London from this coming Thursday (8/08) until the next Thursday. This trip was basically thrown in my lap 45 minutes ago so i havn't had much time to do research.

I'm going to be staying w/ some family there and i guess they live right by Piccadilly Sqaure (or is it a circle, i don't know, some damn shape).

Anyhow, i was hoping some of you guys could throw out some possible things to do and/or places to see on a budget.

thanks.
