Streetza - Milwaukee, WI
This van-tastic mobile pizzeria is known for many things as it blazes its way across the streets of Milwaukee. One of them is "crowd-sauced" pizzas, a way of ensuring that their roughly 10,000 Twitter followers can find toppings on pizzas they like. And these are not just ordinary toppings. At Streetza, you'll find mac 'n' cheese, s'mores, bratwurst, Girl Scout thin mints and even things like crab legs on pizza (left). No word on if they dispense bibs.
