IGBIS is served by two cafeterias, one for elementary and one for secondary. This allows the school to better cater for the developmental readiness and preferences of different ages. Fireflies, Early Years 1 and Early Years 2 students are served their lunches in their own classrooms.
Students are able to choose from Asian, Western and vegetarian options, as well as sandwiches and gourmet bread options. Breakfast and snacks are also available. Meals are planned in advance to ensure a variety of options. Payment is made electronically so that no cash needs to be carried by the students.
The IGBIS Cafe, located near the Theatre, provides a selection of hot and cold beverages as well as pastries, fresh sandwiches and other hot and cold dishes. Visitors may purchase meals from the cafe using either cash or the cashless system.
