Seattle-based startup Order Mapper is tackling that problem with an iPhone app launched today called Order Pizza. You enter your contact information, pick a nearby pizzeria, select toppings and the size from a menu and press order through the app.
It then makes a call using Twilio, which has a powerful application programming interface for phone services. The automatically generated phone call uses a recorded voice to read your details to the pizzeria. It sounds like a customer service phone tree, except the tables are now turned and the pizzeria has to listen to an annoying phone menu of your order. Payment is analog: you pay with cash when the delivery man gets to your door.
