After 5 or 6 trips to Vinci, I would rate this as a great restaurant. The food is straightforward, but it is always very well prepared and flavorful. The hen cooked under a brick and flavored with citrus is great. I had a special one night of grilled whole fish that was outstanding. The service is also great.
Service is generally impeccable.
The worst service I have had there, which was on one trip, was still better than most places. Mo One of my favorite restaurants in Chicago, no trip would be complete without dinner at Vinci. IL Arrived 5 minutes before the reservation and was told that it would take 10 minutes to be seated. Sounded reasonable but did not get seated for nearly an hour. Making amends was very slow in coming and not well communicated, as though the host was waiting to see how much of a point we would make of this error.
