The Tower is on the housemate's must-see list; she's been reading about the Ravenmaster, and is keen to see the Ceremony of the Keys. And if the Sherlock Holmes museum isn't on her list, it should be.

I think visiting the South Bank, the secondhand book stalls under Waterloo bridge and the street food there is an unmissable - plus you can see some Pros backgrounds! *g*

Ooh! It happens that I plan to do a lot of secondhand book shopping, and I adore street food. This definitely goes on the list!

Many thanks for the tips!
