If Busch-fortified, Maull’s-slathered Boston butt is a Saturday afternoon cookout, Your Place Diner’s (5510 Virginia Avenue, 314-260-9069) smothered pork steak is Sunday supper at Grandma’s. Slow-cooked to the point it falls apart at the mere suggestion of a knife prod, the tender pork is both a worthy component in its own right and a canvas for rich, meaty brown gravy that soaks into every crevice.
