I have called regarding Thanksgiving dinner plans for a few different restaurants. California Grill and 1900 Park Fare are pretty picked over for available times. However, I did ask about Garden Grill and the CM told me there are a bunch of available tables. I have not been to Garden Grill personally, but it seems to get good reviews generally. It might be a good option if you want to get a particular time. Another restaurant that seemed pretty popular for TG is Chef Mickey's, but I have a feeling the times there will be slim pickings, also. Good luck with whatever you choose!
