The music was louder than usual inside. But no one had tampered with the volume knob. That hadn’t changed since December 13th 1979, when John Zawisny, along with his dad and brother, opened Eagle Provisions at 628 5th Avenue. Real estate agencies have come to call the neighborhood South Slope, but 35 years ago, the area on and around 18th Street in Brooklyn was just another enclave of city dwellers paying cheap rent. And like most pockets of urban environments, this one was comprised of folks from like heritage. In this case, Polish. The Zawisnys setup shop and began selling provisions to sustain this community.
