As we’ve played Grease and we’ve learnt about the big work, effort and dedication that this entails, I think we should visit Shakespeare's Globe Theatre. This theatre is a replica of the original stage of Romeo and Juliet. It could be interesting because the history of the theatre, the story to relate is very romantic and we’ll like it, we’ll listen to the English dialogues and learn from the actors. Moreover, its price is quite cheap and the place is not far from the underground.
In my opinion, it is a unique opportunity.
We’d also take the opportunity to visit Tate modern. This museum has got some very curious works of art.
And to finish, a trip around the River Thames crossing Millennium Bridge.
Here I put some links where you can find more information about prices, opinions, photos, etc.
