If you are looking for somewhere a little different to have your lunch then how about the outdoor restaurant at Petersham Nurseries in Richmond?
Set on a sandy floor and surrounded by exotic plants you might think you were in some sort of Dynasty orangery setting.
The restaurant at Petersham Nurseries is only open for lunch not dinner and offers a produce led menu that changes seasonally. The food is supplemented with edible flowers and herds so a perfect option for this week what with all the flowery bits and pieces going on in London.
The surroundings are wonderful and really worth a trip to Richmond for if you live in another part of London. You can always have an afternoon wonder around the nursery afterwards and take a little something home with you.
