We love Chef Mickey's, but we prefer breakfast there. Dinner really didn't do anything for us. We also enjoy the crystal palace, so much we've been known to do breakfast and dinner there in the same WDW trip. Didn't care much for 1900 Park Fare but that was more of a parents not controlling their children issue.
I would also vote for Chef Mickey. The last time we were there the food was great and there were many characters and great energy. However, I do find that it is too busy and we had to wait quite awhile for our table.
Crystal Palace for breakfast..........fantastic food & great character interaction. It's DH's only request when we vacation there - breakfast with Pooh & Friends.................
