Virtual Waiter at Pizza Hut

Evan Schuman reports on Pizza Hut's Virtual Waiter Program. They say this takes data from millions of online orders and suggests add-ons to your order like Amazon does. Beyond the usual data, it also uses location from zip codes. What complex pizza ordering patterns exist in these orders remains to be seen. At the very least it exposes some of your other offerings to your customers, as effectual as a waiter saying 'would you also like an order of garlic sticks'? A common up-sell at restaurants. It's not like books ... to what extent does the fact that others order something with pizza influence you? They should soon have that data.
