After visiting the Royal Castle of Chantilly, book a table in this luxurious inn abutting the gardens. In a lavish setting, dripping with fine art, chandeliers and tapestries, diners sample unabashedly creative cuisine with a weakness for vegetables and seafood: gyoza-style veal and eels, tarragon-flavoured labneh; wild turbot, salsify, za’atar and cognac with a peat-flavoured, roast chocolate extravaganza to finish. At Le Jardin d'Hiver bistro, traditional and seasonal dishes are served in the gallery or on the pretty patio.
