What does "up-selling" mean in a restaurant context?

In the context of a restaurant, up-selling refers to the practice of encouraging guests to select more expensive items or add-ons to their meal. This can include suggesting premium versions of items, recommending side dishes or drinks that enhance a guest's experience, or promoting higher-priced specials. By effectively up-selling, servers can increase the overall check total, benefiting both the restaurant's revenue and potentially the server's tips.

This approach relies on building a rapport with guests and understanding their preferences, enabling servers to present options that align with the customers' desires while also elevating their dining experience.
