The Sterns have been eating at Leon's Bar-B-Que in Chicago's South Side for as long as they've been together. They go for the spicy, meaty spareribs, rib tips and hot links - spicy sausages bathed in zesty barbecue sauce. It's soul food as good as it gets. The only down side is ordering and paying through a bulletproof window. The Sterns say go to Leon's during the day and eat in your car.
