I would vote no to either of your posted selections. I think that the HDDR is overpriced and Chef Mickey's for dinner is the worst meal on property.
Depending on which park you are going to be in for the day, then I would choose something there.
For instance, if you'll be in the Magic Kingdom, then I would strongly recommed the Crystal Palace.
At EPCOT, Le Cellier, the Rose & Crown or the Garden Grill are all nice choices.
At MGM, definitely would vote for the 50's Primetime Cafe, then view Fantasmic.
If you are looking to dine at one of the resorts, then my votes would be either at O'Hana's at the Polynesian or at the Whispering Canyon Cafe in the Wilderness Lodge. Both are wonderful.
