"Crust Fund Pizza is the little pop-up that could. From John Carruthers, a home chef and marketing professional for Revolution Brewing, Crust Fund is a way for him to showcase his passion for pizza. He takes orders via Instagram (drops happen monthly). Customers don’t pay Carruthers though; they donate money to a charity of his choice in exchange for the secret back alley location where they can pick up a pie. The pizza is mostly Chicago thin crust, but look for a variety of specials. And be quick to lock in an order as drops sell out instantly." - Ashok Selvam, Eater Staff
