Which London show to take a 16 year old girl to!!

[GrumpyOldMan100]

As someone who's never had kids, I'm hopeless in their company!!
But I'm lucky enough to have a wonderful Peruvian goddaughter who's now 16.
She's currently studying in Germany but is coming over for a weekend in a month's time and I'm struggling to decide on a suitable London show to take her to!
She's been to stay with my wife and I before and we've taken her to Lion King (she's known the story since very young), the School of Rock (easy story to explain), Dick Whittington at the Palladium last Christmas (had to explain story to her) and The Show That Goes Wrong (very visual humour).
While some way to go with her English fluency, I think her English is pretty good. She understands more than she let's on.
Any suggestions please?? Help!!!!!!
On previous visits she's seen quite a lot of London's famous sights - so, in addition to a show, any suggestions for lesser known places in London to visit that would intrigue and stimulate a 16 year old girl?
Thanks in advance.

Do you think she’d like Matilda or Thriller? As for sightseeing, has she been to London Zoo or Harrods?

Mamma Mia, Wicked or Chicago? I took a friends daughter to see these and she loved them

As for sights for a 16yr old..... depends what there into but maybe head to the shard, globe theatre is fun and you can get standing tickets for £5, Camden market, Boat trip to Greenwich and wanderto the observatory and to the market,

Thanks for these suggestions. I've now booked Mama Mia on recommendations from Mumsnet folk! This girl loves animals (going for a walk is a nightmare because she stops to stroke every dog we pass!), so we've certainly done London Zoo in the past. And Harrods.

For sightseeing Tate Modern is one of my dd’s favourite places, Camden being another. Lots to do or see at both and very easy to get to on tube

Agree with Pawprintjoy The Tate Modern is cool and it has the viewing area.... all free too! I would have suggested booking the 'Ceremony of the Keys' at Tower Bridge. That is brilliant but you need to book at least a year in advance and is only a pound. Maybe next visit?

One of the rib speedboats down the Thames? If she likes Harry Potter there is the minalima gallery which has original artwork.

Thanks very much for these additional suggestions - my plans are coming together nicely thanks to all your help!
