What term is used for items served that do not change frequently on a menu?

The term used for items served that do not change frequently on a menu is known as a standard menu item. These items are consistently available, making them a staple of the dining experience at a restaurant or food service operation. A standard menu item often reflects the brand's identity and customer preferences, ensuring that guests can expect certain familiar dishes every time they visit.

Standard menu items can enhance operational efficiency since they streamline inventory and training processes. Staff can become proficient in preparing these dishes, and customers can rely on their availability, which can build loyalty and encourage repeat visits.

In contrast, other terms pertain to different aspects: nutrient-content items focus on specific nutritional characteristics, variable menu items imply a level of change or seasonal adjustments, and self-service items indicate a different style of dining experience where patrons serve themselves rather than being served.
