Finger-licking ribs this good just can't be Northern barbecue.. In Short Eat at this chain and you'll swear the Mason-Dixon line moved to Saskatchewan. The weathered-looking wooden walls of Dave's shacks are decked out with roadside signs and cute pig paintings. You stand in line to order, then take a numbered wooden pig to your table. The sandwiches and platters (including Texas beef brisket and Georgia chopped pork) are filling, but favorites include a mess of St. Louis-style ribs, sticky with Dave's own award-winning sauce.
