In what looks like an oversized kiosk-cube, this restaurant is truly 'under the crown' thanks to a dangling sculpture in its glass topknot, and there's an L-shaped balcony for summer seating perched above the former palace moat. Expect good-quality, seasonal fare, the lunches favouring traditional recipes and short dinner menus offering at least one fish and one steak option.
For dessert try the home-grown rhubarb.
