1. Fixed Menu: A fixed menu is a type of menu that offers a set list of dishes for each meal. The menu does not change and stays the same every day or at all times. It is usually used in fast food or chain restaurants.
2. Cyclic Menu: A cyclic menu rotates the dishes on a set schedule, such as weekly or monthly. The menu is designed to offer variety and is used in institutions like schools, hospitals, and cafeterias, where food offerings change periodically to prevent monotony.
