Laft City was a theater located in Gotham City.
History
Long after it closed and became derelict, the Joker used the Laft City theater as his hideout. One night, back in the theater after escaping from Batman, the Joker kicked out Harley Quinn for screwing up his opportunity to kill the Dark Knight with one of his guns. However, as the hideout became a mess due Harley's absence, when the Joker became aware of Harley's successful partnership with Poison Ivy, he along with his henchmen Rocco and Henshaw went to search after them to steal their thefts.[1]
