Some restaurants have a multi restaurant ordering system that allows customers to order from more than one restaurant at the same time.

The benefits of multi restaurant ordering system are:

- Customers can order from multiple restaurants without having to call each one individually and wait on hold.

- The process is faster and more convenient for customers. They can make their orders in advance and then pick them up at their convenience.

- The system also saves time for the restaurants by reducing phone calls, waiting times, and customer turnover.

- A database of all restaurants' menu items, menus, and hours.

- The ability for the restaurant to contact customers by text message or email to let them know about new promotions and specials.

- Reliability, so that when a customer chooses a restaurant on their app it will always be closed or open.
