imperial war museum in sem-close proximity to restored globe theater, you could do those in the AM, catch lunch at a pub on the south side of the river, then walk across tower bridge and hit the tower of london.

or, if you want to do more central london-based stuff, hit the cabinet war rooms. under / behind ten downing street, this is the bunker churchill lived and worked in during the blitz. really cool, and do-able in less than an hour.
