After visiting the Royal Chateau of Chantilly, book a table in this luxurious inn abutting the castle’s gardens. In a lavish setting dripping with fine art, chandeliers and tapestries, diners sample unabashedly creative cuisine with a soft spot for vegetables and seafood: goat’s curd cheese, brocoletti and fingered citron, roast John Dory, BBQ sausage and Cajun aubergine; figs, emulsion of unpasteurised milk and honey vinegar. At Le Jardin d'Hiver bistro, a traditional, seasonal score is served in the gallery or on the pretty patio.
