Great place to visit. Most of it is free. Can take a long while to see the dinosaurs as they are very popular and often have long queues. Is a must to see if you visit London!

For the natural science buff, this is the place to go!! The building is old yet very well kept. The dinosaur and gem exhibits were awesome. There were exhibits on animals (even stuffed dogs). The employees were very helpful and friendly. If I had a chance to go again, I would in a heartbeat.
