It's true that Philadelphia's downtown is an incredibly convenient place to do business, with government offices, top companies, shops, and restaurants all clustered within easy walking distance. But Philadelphia's center of gravity has been gradually shifting westward. The near-completion of the Cira towers on the west bank of the Schuylkill speaks to that, as does Aramark's decision to move into the former Marketplace Design Center. Penn and Drexel have expanded their spheres of influence well past 40th Street, and now virtually bump up against the Provident's largely residential Mill Creek neighborhood. Children's Hospital is already there, having established a beachhead in 2013, when it opened an outpatient clinic, the Karabots Pediatric Care Center, at 48th and Market.
