I think it is called Microsoft Surface.
Even better, the surface tracks what's on the table and associates it with the customer. Like a credit card (RFID), a receipt, a plate, a glass (The table recognizes the markers underneath the utensils). Or if it was located in a vacation spot, manage the photos they've taken while waiting for their order.
On the other hand. Why didn't they just opt for an android tablet, they're cheaper and they can put in their own software and updates without needing to go through the istore.
