Laying over at O'Hare for nine hours, I asked a large police officer with an Italian name for the "Best Italian Restaurant" in Chicago. He sent me through the subway to Monroe station, up to the street and into "Italian Village" -- so authentic that I thought the don in the three-piece suit in the booth next to me would be machine-gunned any minute.
A huge menu and a long wine list were my two favorite aspects of this VERY authentic spot. Must have been a dozen veal dishes (I went with the saltimbocca) and scores of Chianti's (tried a big Tuscan Classico). Better than Roma or Napoli -- with all due respect to the originals. Not a place to dine alone, but it sure beat the airport options. The antipasto plate would have made a good light meal in itself.
Dessert, service and atmosphere were all impressive and came at a moderate price. Hope to be laid over in O'Hare again soon.
