Ok shite title but I'm tired (AF is visting and brain cells go dormant!) Seeing Santa at Selfridges this Saturday evening and would like to make a day off it. I'm looking for ideas that the kids (4 & 5 year old)will love and not too pricey for us adults please. Was thinking of Natural History Museum or even Science Museum (someone told me it was better for older kids???), somewhere nice to eat but not too pricey and anything else that is on the way????????
