What type of restaurant system primarily relies on technology for menu management and promotions?

The option referencing digital menu systems is correct because these systems leverage technology to streamline menu management and facilitate promotions. Digital menu systems allow for dynamic content updates, meaning menu items can be changed in real time based on availability or to highlight special promotions. This capability enhances customer engagement and can drive sales by easily showcasing limited-time offers or new products.

Additionally, digital systems often integrate with other technology platforms such as point-of-sale systems, enabling better inventory management and analytics. By analyzing sales data, restaurants can make informed decisions about menu items, pricing strategies, and promotional efforts.

In contrast, traditional menu boards, manual order systems, and printed creation menus lack the flexibility and immediacy provided by digital solutions. These methods often involve static content that requires more time and effort to update, making it harder to respond quickly to market changes or promotional opportunities.
