I'm taking my daughter and her friend to London to celebrate her birthday. We have found somewhere we like the look of to go for lunch and now we are looking for other fun ideas. Lunch is in Covent Garden. We wondered about finding somewhere fun to go for a pudding if anyone has any good ideas and just other ideas to while away the afternoon doing nice things. We have done various museums etc so are looking for something maybe more like an experience or a cool place to visit. Any recommendations please? Thank you.
