Your shopping list may include robust regional wines, Dijon mustard, antiques, and the black-currant cordial cassis (try a splash in champagne to make a kir royale). The best shopping streets are rue de la Liberté, rue du Bourg, rue Bossuet, and (for antiques) rue Verrerie.
The market at Les Halles Centrales, rue Odebert, sells fruits, vegetables, and foodstuffs on Tuesday, Thursday, and Friday from 8am to noon, and Saturday from 8am to around 5pm. A separate endeavor that specializes in used clothing, kitchen utensils, housewares, and flea-market castoffs, Les Marchés autour des Halles operates along the market's periphery Tuesday and Friday from 8am to noon, and Saturday from 8am to around 5pm.
For the ideal picnic lunch, begin at La Boutique Maille, 32 rue de la Liberté (tel. 03-80-30-41-02), where you can purchase many varieties of the world-famous mustard. Follow with a visit to the Crémerie Porcheret, 18 rue Bannelier (tel. 03-80-30-21-05), to pick up several varieties of regional cheese, including citeaux, made by the brothers at a nearby monastery. Finish your journey at one of the three locations of Mulot et Petitjean, 1 place Notre-Dame, 16 rue de la Liberté, or 13 place Bossuet (tel. 03-80-30-07-10), where you can pick up a pastry (especially gingerbread) for dessert.
For antiques, try Monique Buisson, 21 rue Verrerie (tel. 03-80-30-31-19), which offers a good collection of regional furniture from the 1700s, or Dubard, 25 bis rue Verrerie (tel. 03-80-30-50-81), for 19th-century garden ornaments and contemporary upholstery fabric. Other choice stops include Aux Occasions, 29 rue Auguste-Comte (tel. 03-80-73-55-13), where you can browse through a multitude of mainly English antiques from the 1800s, as well as old and new Oriental rugs. Also appealing is Antiquaires Golmard, 3 rue Auguste-Comte (tel. 03-80-67-14-15), which specializes in objects originating on private estates in the region. This store is flexible about trading antiques with individuals and other dealers, making it something of a clearinghouse for unusual antiques from throughout Europe. Le Consortium, 16 rue Quentin (tel. 03-80-68-45-55), is one of Dijon's most interesting modern-art galleries.
