The history of the Green Mill Restaurants begins with the oldest licensed pub in St. Paul, Minn., the Green Mill Inn. Started by Myron Roth, the Green Mill Inn began as a soda fountain in the early 1930s, and it has continued as a neighborhood pub since that time. In 1975, Chris Bangs, Larry Cardoni and David Bicanich purchased the Green Mill. Within a year, using Cardoni's family recipes and some impromptu food science performed by dissecting the deep-dish carryout pizzas of 30 Chicago pizzerias, the group introduced its Chicago-style deep-dish pizza. Green Mills Restaurants has garnered more than 30 awards from food critics of publications, such as the St. Paul Pioneer Press, Minneapolis Star Tribune, Twin Cities Reader and Minneapolis St. Paul Magazine.
