United surprised us in Chicago with a new club in Terminal 2, on the E concourse side. It was opened to supplement the upstairs one between E & F and has some newer features that the GM said they are trying out, including; enclosed backlit Zoom Pods (I think those will be a big hit), a self-service bar that even includes tap beers and tap sparkling wine (Prosecco). It well staffed and renovated, this was most recently the Delta Club and long ago I believe it was either the Continental or US Airways Club. I have a full video review if you are interested.
