The Rookery is an ornamental garden on Streatham Common. It is on the site of an old guest house, now gone, where Queen Victoria used to visit, to take the water, from the three springs, on Streatham Spa. It is still a very pretty, well maintained garden with long views over South London and the South Downs.
The Rookery Café is a nice, old style, park café, with indoor and outdoor seating. There are pleasant views from the outdoor tables. It is child and dog friendly. It has bowls for water and dog treats in a jar on the counter.
It has a good selection of hot and cold food. It has vegan, vegetarian and gluten free choices. It has a well maintained community noticeboard offering everything from local plays to invitations to join a brass band.
It is on the Capital Ring, near the end of Section 5, a very pleasant place to stop for refreshment, if you are doing that walk.
