The kindergarten allows the parents (caretakers) to select daily the menu for lunch. There are over 30 possible items to be included in the lunch menu. For a lunch item we keep a code, its name, and the number of calories. A parent (caretaker) can make for each of his/her children a lunch order everyday. If no order is made in a day the last order made will be provided. An order consists of a maximum 4 items. Same item can be ordered multiple times and fewer than 4 items can be ordered.
