The Canonbury is a pub in Islington which has a large garden area, so a lot of families with children come here on a weekend with their children for brunch and lunch. My boyfriend and I met up with such a couple that has 2 kids and had brunch here. The day was sunny and warm and it was a pleasure to sit outside in their large and nice outside space and drink a slightly alcoholic drink. The food however I thought was not amazing and most pubs do better food, so I would not make this a lunch destination, but if you are here in the garden enjoying the good weather, you could have lunch.
