In Happy Together, the main character Lai Yiu-fai (played by Tony Leung) lives in the neighborhood known as La Boca, literally the mouth of the Riachuelo river. This barrio, with its colorful houses and storied history, is often invoked as as emblematic of Buenos Aires as a whole. The birthplace of Argentinean tango, it is a dangerous neighborhood to walk around in outside the limited tourist district. It is also quite a bit of distance from the city’s center.

Lai Yiu-fai is shown repeatedly catching the bus to and from La Boca from his job at a doorman at a nightclub. I also took the #29 bus, which looks almost exactly the same today.

And here is the La Boca bridge that the two lovers jog across one cold morning:

And lastly here is El Obelisco, located in the center of the city at Avenida 9 de Julio. Wong Kar Wai uses sped-up footage of this monument, which is located in the middle of the widest street in the world, as as a trope to showcase the swift passage of time.
