Petersham Nurseries Richmond
off Petersham Road, Richmond,
Surrey TW10 7AG (020 8605 3627)
Set among meadows, complete with grazing cows and distant church steeples, on a stretch of the Thames known as Arcadia, Petersham Nurseries enjoys the most idyllic of locations. Diners sit at an assortment of wooden and wrought-iron tables in one of the nursery's earth-floored conservatories. The IoS's own Skye Gyngell, formerly a private chef to the likes of Madonna and Charles Saatchi, cooks with seasonal and impeccably sourced ingredients, including fruits and salads from the garden behind her shed-like kitchen. It's unfussy, self-confident and fabulously flavourful – she likens her technique to making music – with dishes designed to run the full scale, from earthy base notes to fresh top notes.
