Answer:
D. a premium rooftop restaurant in the same city.
Explanation:
Golden harvest restaurant is more concerned with provision of high quality dining services to customers. Customers are less concerned with price.
The best option that customers will appreciate is a premium rooftop restaurant in the same city. This will satisfy the customer's need for quality dining.
On the other hand a food kiosk in an adjacent subway station, a mobile food cart parked opposite to the five-star hotel, and a nearby fast-food restaurant will not meet the client's needs.
