Mudchute Park and Farm
Small farm just near from Canary Wharf. We visited on Sunday (July 5, 2015). The good thing is it is FREE, though you can donate through membership. You can buy 1 pound feeds to feed the animals and pet them as well. The animals are quite domesticated and tame.
Nearest DLR: Recommended DLR Stop is Crossharbour (just walk across ASDA car park and you will be at the farm), though you can also stop from Mudchute and Island c

Canadian Brunch (Home-made Banana Bread with Bacon and Scrambled Eggs. Coffee Latte wasn't good though :)
