Prior to booking, your Intents extension provides a set of potential reservation options in the form of
INRestaurant objects, each of which contains a unique booking identifier. When the user selects a reservation time, this property receives the booking identifier from the corresponding
INRestaurant object. Use that value to get the details about the reservation option chosen by the user.
