I ordered some for a birthday/mothers day surprise for my mom next month. We are having lunch at the Grand Floridian Cafe.
There are several threads about them, but they are probably very buried. You might want to do a search. I dont recall anyone saying they were bad =)
They're $8 a piece, and must be ordered in advance through the bakery. Call the GF directly and ask for the bakery... front desk won't have a clue what you're talking about, I found =)
I'll report back in may about the taste! They're white chocolate with a mousse in it, with a chocolate teardrop filled with chocolate mousse beside it =)
