For any nature lover making the trip to Kew, Petersham Nurseries, four miles to the south, is an unexpected find. On the grounds of Petersham House, a 17th-century mansion that grows its own organic produce, the nursery has a restaurant like few others in this leafy district where London abruptly ends. Among the superb dishes are the duck confit with pickled plums and the pears baked in Marsala wine. If you go, just make sure you're sensibly shod. Although your face may be brushing orange blossoms and your plate sprinkled with truffles, your feet will be in the dirt. Lunch, $125. Off Petersham Rd., Richmond; 44-208/605-3627.
