What times of day will you be there? What kind of food do you like? Without knowing your predilections, it's very difficult to make suggestions. Certainly you can take a train to Centraal / Central and walk two blocks to the Rue des Bouchers and its variety of restaurants, not to mention the shopping at Galeries St. Hubert (Galerie du Roi and Galerie de la Reine), and all that lies between there and the Grand Place, for example.
