As you sit in the greenhouse with sand at your feet, surrounded by fresh flowers which even in the winter months perfume the air, it feels as though all is right with the world. A unique spot within the London dining scene, this restaurant forms part of the wider Petersham Nurseries complex, where you can buy plants and homeware to spruce up your abode. The cooking is informed by their own fresh produce and has a clear Italian accent, from beef carpaccio and wild mushroom risotto to pan-fried sea bream with puttanesca.
