There are two main interpretations of the question "how late is subway open":
- New York City Subway system hours: The NYC subway runs 24 hours a day, 7 days a week, including late nights from midnight to 6:30 AM every day. It never closes but operates with longer intervals between trains during late night hours.
- Subway restaurant hours: The closing times vary by location. For example, Subway restaurants in Germany typically close between 9 PM to 11 PM depending on the day and location.
Please clarify if you are asking about a specific city's subway transit system or a Subway restaurant location to provide a precise answer.
