If they even offer food at all, most Houston music venues couldn't care less about how that food actually tastes. And true, most people who need something to snack on while watching a band are more interested in soaking up all that booze than in any kind of fine-dining experience. But anyone who's sampled the fare at Adam and Lena Fisher's barbecue stand in the Continental Club knows the two need not be mutually exclusive. Always on weekends, and usually during the Continental's bigger weekday shows, the Fishers' array of tender brisket, spicy links, rib-sticking red beans and rice and scrumptious hot dogs has headed off many a hangover, and deliciously so, for not much more than the price of a drink. Since the Continental opened its Pachinko Room patio bar this spring, the Fishers have also been serving it up every Saturday afternoon.
