I feel like most Pho spots are like this now a days. Just a QR code to do everything on your phoneI ate at a place in SE Asia, where you shoot the QR embedded on your table and from the link you get the menu and place your order etc. Someone eventually brings out your food. Then you go up to reception to pay. They automatically add a 10% service charge for really doing no wait staff activity but bringing out the food. Thus someone showing you to the open table, someone bringing the food, someone at the register to pay. Approximately 4 words spoken. ("You can sit here.")
