What is the primary function of a restaurant's menu?

The primary function of a restaurant's menu is to serve as a sales tool and to communicate offerings. A menu is the most important marketing instrument for a restaurant; it not only showcases the range of dishes available but also highlights their appeal through descriptions and pricing. By effectively communicating what the restaurant offers, the menu helps to entice customers and guide their decisions, ultimately driving sales. A well-designed menu can influence customer choices, enhance their dining experience, and position the restaurant within the marketplace.

In addition to being a sales tool, a menu helps establish the restaurant's identity, reflect its theme, and communicate the quality of the offerings. It plays a crucial role in customer engagement, as the menu directly impacts their perception of value and satisfaction. This is why the correct answer focuses on the dual role of the menu in both driving sales and providing clear communication regarding the food and drinks available in the establishment.
