Final answer:
The exact number of McDonald's in Manhattan is not provided here; it fluctuates and requires current corporate data or a recent market survey to determine.
Step-by-step explanation:
The number of McDonald's restaurants in Manhattan, like in many major cities, can fluctuate with new openings and closures. However, to get a current count, one would need access to updated corporate data or a recent market survey of fast-food outlets in the area. While there are numerous small restaurants throughout Manhattan, each contributing to the diverse culinary tapestry of the city, the precise number of McDonald's locations in this specific borough is subject to change and would be best obtained from directly contacting the company or consulting the latest business directories.
