This place is magical.. the boyfriend and I visited on our trip last weekend, and were very delighted.
Obviously this shop has many over priced packaged candies and chocolates, but the freshly made tarts and treats are only about $6.50, and they're definitely filling! They also have a wide variety of tasty, creamy gelato to choose from too (also reasonably priced.)
The boyfriend got "Intense" which was a dark chocolate mousse covered in a dark chocolate ganache. Oooh divine! There's nothing bad to say about this. At all. Ever.
I got the Key Lime Tart. It had a white chocolate top, with some kind of lime flavored whipped cream, and tangy/sweet lime curd, and at the bottom was a shortbread cookie.
I strongly suggest if you have a sweet tooth, and are looking for something exquisite, try and stop by here on your trip to Vegas.
(Did i mention the gigantic waterfall of chocolates? It's beautiful!)
