Which service style encourages guests to serve themselves from a self-service area?

Buffet service is characterized by a setup where food is laid out on a long table or counter, allowing guests to serve themselves from a variety of dishes. This style of service promotes a casual dining atmosphere and offers guests the freedom to choose their portions and selections according to their preferences. It is particularly popular for events and gatherings, as it can accommodate a larger number of guests efficiently.

In contrast, à la carte service involves guests ordering individual items from a menu, where each dish is prepared and served by the staff. Cafeteria service typically features a line where guests select items as they move through, but it often includes staff assistance or portion control, differentiating it from a true self-service experience. Room service entails delivering food directly to a guest's room, providing a completely different dining experience altogether.
