The headquarters of Belgian culture in Detroit, the Cadieux Café has the only feather bowling alleys in the United States. The bowling alleys are concave and made of dirt, ox blood and cat litter. Players roll huge wooden wheels and try to land closest to a feather. Tucked away in a residential neighborhood on the east side, the Cadieux Cafe is also famous for its fabulous mussels, which are served in six different ways. The rest of the menu is unremarkable, but the Old World décor and cheery atmosphere, including a small recreation of "Mannequin Pis," a famous Brussels fountain of a urinating young boy, provide a good taste of Belgian bonhomie. Bowling lanes must be booked months in advance, but it's almost as much fun to watch the old-timers bowl on Tuesday and Thursday evenings as to play yourself.
