In Creed, which city does Adonis Creed travel to seek Rocky Balboa's training?

In Creed, Adonis Creed travels to Philadelphia to seek Rocky Balboa's training.

Adonis has already built experience as a professional boxer, but he wants guidance from the man who fought and befriended his father, Apollo Creed. He leaves Los Angeles and moves to Philadelphia, where Rocky runs Adrian's restaurant and remains connected to the city's boxing community.

Philadelphia is important to the franchise because it is Rocky's home and the setting of many defining moments in his life. The city also gives Adonis a way to build an identity separate from his father's fame.

Rocky eventually agrees to train him at the Mighty Mick's Boxing gym. The film uses familiar Philadelphia locations while introducing a new generation of characters, including Bianca Taylor and Adonis's trainer Rocky.
