We went to both in Dec 2007. We went to Chef Mickey for dinner the day we arrived thinking it would be a great introduction to the characters before hitting the parks the next day. I wasn't super impressed with the food but I am glad we went. Before stepping foot into the parks my kids already had pictures with Mickey, Donald, Goofy, Pluto and Minnie. 1900 Park Fare was a favorite among every member of our family. Everyone liked the food, the service was great and the character interaction was some of the best we had ever seen. When we went it was Cinderella, Prince Charming, the Step Mother and 2 Step Sisters. If I had to pick only one dinner it would be 1900 Park Fare. Better food and less chance of seeing all of those characters in the parks. Pretty much 100% guarantee you will see the main 5 in Magic Kingdom alone.
