It's dangerous staying at Wynn - Chocolat is just steps away from one's room. I've sampled many more things than I care to remember, but a few that come to mind are:
* Macarons. Available in a number of flavors, including chocolate, coffee, vanilla, pistachio, and...and...and...pink (now what was that flavor?). They're a combination of soft, chewy, and crunchy, with a creamy layer as well. Very good!
* Something like a candy bar, available in several different combinations of chocolate, nuts, and some other ingredients. Perhaps these were Jason A's "Bouchee"? In any case, one of my favorites.
* Assorted truffles and other chocolates. Good, but not as good as the above.
Are they worth the outrageous prices? Not really, but hey, you're on vacation!
