Jonathan Fraser works at Price-Norbury Memorial Hospital (or does he?). The filming location for the hospital is actually Mount Sinai West hospital located at 1000 10th Avenue just south of Lincoln Center.

You see Jonathan walking in front of the hospital on Amsterdam Avenue while on the phone with Grace. Later, Grace stops by the hospital looking for Jonathan and meets one of his colleagues.
