Really enjoyed Buckingham Palace, I didn’t think I’d be as interested as I was but it was a great experience and all killer, no filler!
I love mooching around the V&A. Just visit a couple of highlight exhibits like the great bed of Ware! The good thing about the V&A is you can pop in and out quickly, or spend hours there.
If you are into art, then the Quentin Blake centre for illustration has just opened. It’s not just his art! The Tate Modern and Southbank are top spots for art and design enthusiasts.
I enjoy mooching around Covent Garden, the little boutique shops and stalls, makeup and perfume shops. There’s a Pilgrims pizza and other affordable places to eat around there.
There are some lovely shopping arcades to wander around, have a coffee, such as Leadenhall, Burlington Arcade.
Tours I’ve enjoyed which you do as a group and can do solo are the street art walking tour near Liverpool Street (Brick lane etc), Jack the Ripper in the same area and the Harry Potter tour (from Leadenhall market).
Daunt books if you’re into books
Afternoon tea in a hotel might be a nice thing to do, St Pancras or something grand
