Gibson's off the River Road exit on 190 can offer anything from a 48 oz porterhouse to a salad. For a light lunch, I really love their crab and avocado salad on the appetizer menu. six ounces of crab, a ripe fresh half avocado, sweet red peoppers and a spicy asian style dressing. If you want a little red meat, they offer a salad with 3 or 4 tourenados of beef, blue cheese, onion and iceberg with a vinagrette.
Even better, you're five minutes from the passenger drop off at O'Hare.
