Exchange student in London - Places to visit

I have pictures from the Goodge St arcade, a bit outdated by the time I left even, but still a good idea. Good times, lots of money spent

 

The British museum is probably the greatest museum ever built. And it is free, just like all museums should be.

 

Thanks for all the response, guys^^ I will definitely check out the most of it.

Are there anyone here who can tell me if "The Lion King Musical" at Lyceum Theatre is something to see? I have heard it's amazing.
