A pizza from a vending machine takes 90 seconds. California Pizza Kitchen is betting on a thousand of them. The chain has partnered with retail services firm T-Roc Global to install and operate up to 1,000 automated retail machines across 30 U.S. markets over the next three years. The kiosks will go into airports, universities, hospitals, hotels and office complexes, places where a decent sit-down meal is hard to find. CPK will fill each market with a cluster of at least 20 machines before pushing further.
