I have not tried all of the nicer places at WDW but, for me Artist Point at the Wilderness Lodge would come closest though Napa Rose is a bit more upscale in decor.
Based on what I have read I think Citrico's at the Grand Floridian would be good as well.
Victoria and Albert's would be a good choice as well, if you want to bring dresses and/or suit coats on your trip.
