Isaly's is a chain in Pennsylvania, Ohio & W. Virginia. An Ice cream store that also sells deli meats and sauces. That have been around a long time.
Actually the original Isaly’s chain of dairy stores no longer exists having closed the last store sometime in the 1980’s. The name is still around as there are several companies selling Isaly's branded products. The dairy store in the Pittsburgh suburb of West View named “I.s.a.l.y.’s.” (if its still there) is decorated like an original Isaly’s store but has no official connection to the original Isaly’s company. Note the use of periods in the name to avoid any legal issues.
