the self order system for all their “quick service” meals, as they call them. A prime example is the new “Be Our Guest” restaurant in the remodeled fantasy land. You use a computer screen to order, you are given a “rose” with an rfd chip in it that you touch to the screen and then you go find a table, they locate you by the rose to deliver your emal.
Other quick service restaurants such as Pecos Bills you use the computer screen and then wait at the pick-up counter to get the meal. No human takes your order.
Many fast food places also use automation to cook the fast food already, not at WDW to my knowledge, but it is possible.
