I, out of obligation to my craft, ordered the hot chocolate after having a complimentary warm spiced wine shot (which was delicious might I add.) So the menu appears to only have one type of hot chocolate- the Ayza Dark & White Hot Chocolate, this is of course assuming that I am reading it correctly and it is in fact one combined type and not two separate drinks. In any case, I drank what they gave me and it was quite good.
The hot chocolate is very dark in color and is reasonably thick. It came with about 30 mini marshmallows on top, which are a nice touch but as they melt they make the drink a bit too sweet to handle. I must say that it was quite a different flavor however, it reminded me a lot of homemade chocolate pudding which I was not expecting, but certainly enjoyed.
So at $6 for a one size fits all, I'd say it is worth a try.
Out of a possible 10 marshmallows I give it an 8.
