This fine restaurant has two Michelin stars and offers classic French cuisine at its most refined. Dinner is served in an opulent Art Nouveau dining room resplendent with swirling woodwork and delicate garlands of wrought iron, and under the influence of chef Lionel Rigolet, service is attentive but delightfully unstuffy. With menus changing seasonally, most of the ingredients are organic and all are prepared with loving care and attention to the most minute of details; menus might encompass cod with Mechelen asparagus or quail stuffed with sweet pepper and artichoke. The wine list is stellar, as you would expect from such an august establishment, which may well be the gastronomic blowout of your trip to Brussels. Book for dinner as far ahead as possible; getting a table at short notice is more likely at lunchtime. You can also choose to eat in the kitchen to spy on the chefs at work.
