I suspect a more sophisticated chatbot will upsell the restaurant's offerings. "Would you like a bottle of champagne chilled and waiting for you? The Mushroom Bruschetta with Brie, Sage and Truffle Oil appetizer is the special of the day" that sort of thing.
Then you get there and find out it hallucinated and ordered you the cheesesteak eggrolls. But this is okay because you love cheesesteak eggrolls and come on... truffle oil? Really?
