Science Museum is a must. It does have so much to see. Plus is Cindy's to the Natural history museum.

And remember nearly all museums and art galleries are free in London. The Design museum is also worth seeing. Depends how much you like art, but the National gallery at Trafalgar square houses some of the most famous works of art in the world.

Want a day out of London. If you like Harry Potter go there. You won't be disappointed. But if in Central London I would just stay there as so much to do. Theatre shows, places to eat, museums, art galleries, exhibitions.

London Zoo. London auarium. Salvador Dali museum. Tower Bridge. Buckingham palace.

I highly recommend you try to visit the Sky Garden.
