Hell's Kitchen  is an area in Manhattan between 34th and 59th Street with a gritty reputation hence the name.
In November 1997, the Extreme Ghostbusters were dispatched to Hell's Kitchen by Janine Melnitz. They encountered an Ecto-Clone eating metal from a dumpster in an alleyway. Disregarding instructions on a quick modification to the Particle Thrower, the team still managed to trap the entity. However, its ions were displaced and two Ecto-Clones manifested. The original team arrived and trapped them by using a parking meter as bait.
- On page 11 of Ghostbusters Volume 2 Issue #9, Peter Venkman mentions the Ghostbusters were sidetracked by a "thing" in Hell's Kitchen.
