This is one of the main attractions on the South Bank. The only bad thing is that it is pretty expencive. On the other hand, there is lots to see. The tour starts in London and goes worldwide, with fishes from all over the world. Populair are the sharks, and they are very impressive. But the most populair are the rays. You can touch them and even if you don't dare it is fun to watch the people touch them. There are also lectures about the wonders of the sea and there is lots to do for children. A nice thing to do on a day in London. As I said, the only bad thing is the price, but combination tickets with other attractions are avaliable.
