London Zoo is slowly getting better. It's trying to make the most of what is, after all, an inner city and relatively small site. So if you visit, accept the fact that, for example, you'll see no more than two tigers, two lions, two gorillas and none of the really big beasts because there just isn't the space. However, there's enough well-curated animals to see and some interesting new exhibits to keep you occupied for 3-4 hours. Unfortunately, the old lion terraces stand empty and forlorn, the old beautiful penguin pool is a rather pathetic water feature (its Penguin Beach replacement is excellent). Worst for me was the giraffe enclosure which is just a patch of asphalt. They've removed any greenery and the viewing/feeding tower, and the space left can't be good for these amazing animals. So there's still much work to be done.
