Market Street Saloon has revamped its downtown location's menu. It now includes the "World's Best Barbecue Sandwich," a half-pound monster of slow-smoked pork topped with homemade coleslaw and your choice of barbecue sauce. If you're looking to try the thing out, for a few precious days, you can get it for only 96 cents (it normally costs $6.99). It will be at both the downtown and North Charleston restaurants today and tomorrow. At that price, you might as well get a bunch to go and freeze 'em for later.
