The Veggie Grill chain has developed a tech stack that includes computer modeling to improve service time. Its first restaurant in Chicago, where it launched the program, has monitors that allow for order anticipation. As the cashier rings up a guest, the order appears on monitors in real time, so the kitchen starts working on food as it’s being ordered. This allows the chain to cut down on wait times, with food ideally prepared by the time the guest pays. The still-developing algorithm is based on previous usage and ordering patterns; it also monitors the product mix.
