Said to be the oldest continuously black-owned restaurant in the city, Ma & Pa's tiny barbecue joint has everything you need, like ribs, macaroni and cheese, baked beans, greens, sweet potato pie and peach cobbler. Customers select sauces to apply at the table. Ma & Pa's keeps a low profile, but if you're packed at lunch every day and you have a regular cast of lifetime customers, you don't need to do much advertising.
