I don't think that enough was made at time of publication of the garden guide which occupies about half of this book. If you live in London, finding out about green spaces can be a slightly tricky business, and Elspeth Thompson visited every single one and tells you what to expect, what looks nice - not just in Hyde Park, or even in Chelsea Physic Garden, but even down to cafes and restaurants and garden centres. Really worth having if you are a nosy London gardener who wants to plan your next snooping expedition.
