The BFI IMAX at London Waterloo is now part of Odeon Cinemas and is hosting kids movies on Saturday and Sunday mornings for only £5 each! Compared to their normal ticket prices of around £17 this is an absolute bargain but no one seems to know about it! At the moment they are showing Disney films and only have two weeks left of their Disney season, Cars 2 on 3rd & 4th August and Brave on 10th & 11th August (check odeon website for times). I have taken my 3 year old a few times now and he loves it! It is the biggest screen in Britain so it is definitely going to be a memorable experience! I would highly recommend it to all parents that they take their kids along...followed by a lovely walk along the Southbank where there are always thing to see!
