ISS offers a nutritious lunch selection for children. The daily menu includes cold sandwiches and salads as well as a hot lunch and soup-of-the-day. Daily vegetarian options and salads are available to students who may have specific dietary restrictions.

Each student is issued a photo ID card that is used in a number of school facilities and serves as the primary means of payment for children purchasing food, snacks or beverages in the Cafeteria. Menus and prices are found in the ISS Community Portal.

Following lunch, students enjoy a run-around on the playground or kicking the football/soccer ball in the ballbinge.
