As mentioned, you are eligible for the newly reopened ORD Polaris Lounge (see picture and menu earlier in this thread) and it has a sit down restaurant. If closer to departure you want to move to an United Club closer to you departure gate, you are also eligible for access to any of the more basic United Clubs.
