Good cheap eats are surprisingly sparse in downtown Chicago, so once a week or so (although never in the winter) I'll shoot out to Chinatown, Little Italy, Greektown, or Pilsen (Mexican neighborhood). Anyplace within 20 minutes or so offering tasty little bites. Or I'll pack a lunch and roll over to Millennium Park or the lakefront to chill in the grass with a book---but we're a couple of months away from that.
