The bar is the heart, in daylight doubling as the lounge, and the way to the terrace and walled garden, from where you can watch boats bob below. At night, it's a magnet for artists, including barflies revelling in their own eccentricities. Tuesdays involve nudity - a life-drawing session at one end of the bar. I gave it a go, but even a G&T failed to help my pencil flow.
