London with teens between 6-8pm?

[user1483390742]

Looking for ideas!
We will already have eaten and need something cheapish/free to do for a couple of hours from 6pm-8pm with 2 teens who are not impressed by very much!
Any inspiration greatly received!

What time of year will you be in London?

Where about?

What time are you eating? 4pm???
Cinema? Tussaudes?

Sky Garden? It's free but you need to book tickets in advance.

London eye?

Could go somewhere 'cool' like coal drops yard or mare street market for a coffee. Or to Pop Brixton/Brixton Village/ boxpark shoreditch. They are some cool places with a buzz about them and where the hipsters hang out.

South Bank for skateboarding? you can watch/ eat etc

Agree to find a cool area to wander and people watch ...

If they aren't from London they might find whitechapel interesting - I always feel a real culture shock getting off at whitechapel tube - there is an art gallery or you could just walk the full length of Brick Lane from shoreditch to whitechapel or other way round.

Namco on the Southbank for loads of arcade games, bumper cars, pool, karaoke and an escape room oh, and cheap wine for the grownups!
