Next time you’re in town, look me up.
Natasha walks along a Budapest street on her way to the safe house.
This street corner is Népszínház utca at Auróra utca, in Budapest. There were some other scenes shot at this area that showed up in the various trailers, but were not included in the film, including one of Natasha walking by a gyro shop (as seen below).
