City Supermarket is a retail chain of 24 hour supermarkets in New York City.
A City Supermarket was the final haunt of Big Green. Like the other places he terrorized, much of the market was either eaten, covered in slime, or in shambles. Peter Venkman utilized a store mirror to bounce a modified Proton Stream off of and strike Big Green, separating him from Slimer. Due to the huge amount of ectoplasm, pinpointing Big Green became an issue. Winston Zeddemore asked Slimer what'd he eat among everything in the store. Sure enough, Slimer led the guys to frozen foods where Big Green was gorging on Popsicles. They trapped the ghost once and for all while Slimer helped himself to some frozen treats.
