Dijon lies in the region of burgundy, a largely rural region famous for its wine. It is a sweet little city with a few medieval half timbered houses and lots of white stone buildings. The city itself is famous for mustard which has been an important industry in the region for hundreds of years. They also make a spiced cake that is reminiscent of gingerbread. Beef is also raised the northern section of the region and boeuf bourguignon is a local specialty. Dishes cooked in wine sauce like coq au vin and oeufs en meurette as well as escargot. All the wine is excellent, but it is a region that has been recognized for some time for its wine-making so is a little more expensive than other areas.
