The All Night Deli  is a grocery store and delicatessen with extended evening hours somewhere in Manhattan.
After Slimer's initial transformation into Big Green, the first place he haunted was the All Night Deli. Big Green covered the place in slime and ate nearly everything, all without taking a number. During the bust, the Ghostbusters demolished the delivery entrance with their Particle Throwers and Big Green got away.
- In Ghostbusters International #2, on page 5, in panel 1, the neighborhood is based on a corner of East Houston Street in the Lower East Side. All Night Deli is a stand-in for Katz's Delicatessen at 206 East Houston Street.
