Pi-On-Wheels

The mobile forerunner of a St. Louis-based pizza joint set to open this summer, the Pi truck's slinging award-winning cornmeal crusted deep dishers like the sausage/mushrooms/ green bell peppers South Side Classico, and the portobello/ Kalamata olives/ red bell peppers/ zucchini Berkeley, all of which you can purchase with a credit card via a high-tech phone plug-in device from Square, presumably named for swinging ladies' men who developed it.
