They using a ordering system call i-comit.
1. They let their customer tick in the ordering at a prepared menu paper on table.
2. Then, they collect it and input the order at a touch screen machine which installed i-comit system.
3. The system will automatically sort the order according type for example drinks, toast, hot meat like nasi lemak, mee soup, laksa....
4. The order after sort will transfer to kitchen and print out a resit at cashier counter.
5. At kitchen, the order of drinks will print out in piece of paper to read by the drink maker, the order of hot meal will print out at chef department for them to prepare, toast order will print out at toast department.
