In the film New Year's Eve, which city hosts the interwoven holiday stories?

In the film New Year's Eve, the interwoven holiday stories take place in New York City.

The 2011 romantic comedy was directed by Garry Marshall and uses an ensemble structure. Its separate storylines follow characters whose lives intersect around New Year’s Eve in Manhattan. The cast includes Hilary Swank, Halle Berry, Robert De Niro, Ashton Kutcher, Sarah Jessica Parker, Zac Efron, and Michelle Pfeiffer.

The movie’s central public spectacle is the Times Square ball drop, which connects the fictional stories to one of New York’s most recognizable real-world celebrations. Several scenes were filmed in New York, while production also used Los Angeles locations and studio work.

The title can cause confusion because New Year's Eve is also the name of the holiday itself and of other media projects. This question refers specifically to Marshall’s 2011 film, not to a television special or a general celebration. Its setting is New York City, rather than Los Angeles, where much of the production occurred.
