Ok have done all the museums to death, so looking for some new ideas if possible. Would like to take ds (15) in, we haven't been to London for 6 months or so.
May also bring one of his friends, but if I do that it will really be more a matter of making sure they get though the tube system ok and leaving them to their own devices for an hour or so.
DS is mad on gaming, not intersted in clothes shopping.
Any ideas gratefully received!
