1. A method, performed by a restaurant service system, for assessing the accuracy of estimated delivery time provided by a restaurant within the restaurant service, the method comprising:

  • receiving a set of orders from a set of diner devices;

    sending the set of orders to an on-site service appliance disposed within the restaurant;

    receiving an estimated delivery time for each order in the set of orders from the on-site service appliance;

    determining an order actual delivery time for at least one order in the set of orders;

    retrieving a set of GPS locations of a set of delivery drivers from a database, wherein the set of delivery drivers are associated with the restaurant, the set of GPS locations are associated with a time period including the estimated delivery time of the at least one order, wherein the set of GPS locations is received from a set of delivery driver mobile devices corresponding to the set of delivery drivers;

    selecting a time associated with one GPS location in the set of GPS locations;

    assigning the selected time as the order actual delivery time for the at least one order;

    determining an accuracy measure of estimated delivery time for the restaurant;

    storing the accuracy measure of estimated delivery time for the restaurant into the database;

    computing a set of delivery time variations from the estimated delivery time and the order actual delivery time of each order in the set of orders;

    deriving a set of statistical measures from the set of delivery time variations;

    generating an accuracy measure of estimated delivery time for the restaurant;

    storing the accuracy measure into the database;

    receiving a new order request for the restaurant from a first diner device;

    retrieving an estimated delivery time for the new order from the restaurant;

    retrieving the accuracy measure from the database;

    based on the accuracy measure, generating an estimated delivery time assessment message; and

    sending the estimated delivery time and the estimated delivery time assessment message to the first diner device, wherein the first diner device displays the assessment message on a screen of the first diner device.
