The Tower of London. A great tourist attraction. Great history…. and a bloody Magikarp nest.
Still can’t complain, picked up a couple of Dratinis here (not enough to call it a Dratini nest) and also picked up the infamous Pikachu. Pikachu is the only Pokemon in the game that I have encountered so far that actually uses a voice rather than computer-generated screeches and squeals for its signature call.
