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 capital's 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 – try a seasonal vegetable medley to make the most of it – and has a clear Italian accent, from crudo to tortellini.
