I chose Beaches & Cream. We have a Ghirardelli's at Downtown chicago and we always hit them when we spend a day there. so, Ghirardelli's is not that "special" I picked Beaches because it's a Disney place as opposed to a place you can visit on other vacays.
I have done the Plaza once way back when... can't even remember how long ago, but it did stick out as anything special. I haven't been to the other 2 places. so I guess my vote is a little off for accuracy.
