So that later only with voice command the user can order food via Google Assistant and stay take it yourself in the store without the need to wait long.
How it works is quite easy. Users only say Starbucks or Dunkin Donuts in Google Assistant, after which it will find the nearest location and ask if the user wants to take orders from the store. Otherwise, the user is also given the option of another desired restaurant location.
This capability is available for any device already supported by Google Assistant. Currently, temporarily, the service seems to be available in the United States.
