The London dungeon in Tooley Street, 5 mins from London Bridge and near to "on yer bike" bike shop!
OYB moved...good luck finding it hidden away under Southwark Cathedral. It's really quite rubbish now...That said, I am glad it moved, my bike got nicked from outside there
May I be so bold as to suggest that the London Dungeon is perhaps not suitable for a 5 year old... I remember having nightmares for months after looking at the guide book that my brother brought home after a school trip...I can still see those photos of the dummies with the plague

and the Hung, Drawn and Quartered dude with his guts spewing out!! Not to mention the skeleton in the gibbet (this was 30+ years ago, I reckon I may have PTSD)
