Thank you, loads of great suggestions 
We’ve done quite a lot, been to most of the museums, haven’t been to the Transport or Science museum though. Have read lots of positive reviews about the Horniman Museum, so that’s another possibility.
We have walked across all of the bridges (I couldn’t look down when we walked across The Millenium Bridge) and briefly walked down The Southbank last year but we were pushed for time and I vowed we’d return. Looked like lots going on.
We’ve walked down The Mall which was great when we went last year as they’d closed it to traffic, down to BP, then to Leicester Square.
Took the clipper to Greenwich, think we came back and got off at Westminster.
St James’ Park, thought we were seeing things when we spotted a Pelican, mad!
Been to The Sky Garden, LOVED this.
Loads more to do and see though, it’s just finding those hidden gems. You’ve all given me lots to think about.
First day we’re heading to Greenwich for the Dinosaur experience, which is only 70 mins long. We don’t get there until about 4 ish though so might be having a bite to eat in Greenwich afterwards. Think I’ve read there’s a Wagamama’s in Greenwich, worth going?
Any other eateries you could recommend?
We’re going in s few weeks time just for the weekend. Goes so quickly though so I have to be organised with an itinerary
otherwise we’d wonder around aimlessly.
