If you haven't already paid the wonderful Mudchute Farm on the Isle of Dogs a visit, you absolutely should. Not only do you get to experience the rare joy of seeing skyscrapers and farm animals together, you also have the chance to feed the animals, enjoy a farm kitchen and even embark on a series of countryside courses if you so wish. And it's free to visit too. Take a look at some of their residents...
Mudchute Farm is free to visit (although donations are encouraged) and open every day. Check out their website for further details.
