This bar is located inside the NY-NY casino, right next to the Hershey Store store entrance. It's exactly what it says: a bar that serves specialty chocolate alcoholic drinks. They also have a regular drink menu in case you start having a seizure from all of the sugary drinks, (but as with all Vegas bars, don't expect any craft beers on tap).
I had their, "Reese's Peanut Butter Cup Martini" made of Castries Peanut Butter Rum, Three Olives chocolate vodka, Marie Brizard Chocolate Liqueur, and topped with small Reese's Peanut Butter Cups; (see my photos below). It was really good but SUPER sweet. As much as I love chocolate, it was even a little too sweet for me. But don't be fooled: it was still a legitimate martini. I was definitely tipsy by the time I was chowing down on my Reese's Peanut Butter cups.
The only negative about this place is the ambience: the bar is really small (I was expecting a lounge or cafe) and I wish the aesthetics of the bar matched the coolness of the drinks. Ironically, the bar looks like any normal bar in Vegas. It would have been nice if the look of the bar was as fun and colorful as the Hershey store.
