Pittsburgh neighborhoods used to be full of little corner groceries. Most disappeared when big chain supermarkets took over the grocery trade. But occasionally a neighborhood store succeeds; this one in Beechview moved into a storefront that was vacant for some time and seems to be making a go of it.
Of course it used to be that your average corner grocery was only four or five steps from a streetcar line. That is no longer true in most places, but it is still true in Beechview.
