Which of the following food service styles offers a menu where each item is priced separately?

The correct answer is À la carte, as this food service style is characterized by a menu where each item is priced separately. This allows guests the flexibility to choose individual dishes according to their preferences and budget, rather than selecting from a set menu or pre-determined choices.

In contrast, Table d'hôte typically features a set menu with a fixed price that includes multiple courses, offering limited options to the diners. Buffet dining allows guests to serve themselves from a selection of dishes without individual pricing, leading to a communal or casual dining experience. Banquet service is often a type of special event catering where meals are predetermined and served at a fixed price, usually for a larger group. These distinctions highlight why À la carte stands out for its individual item pricing.
