Slideshow: We Drink All the Hot Chocolate at Hot Chocolate

Eggnog
Eggnog
You will enjoy this one if you are either a fan of eggnog or white chocolate, but you can also be neither (like me) and still enjoy it. Though I thought it could be heavier on the nutmeg, it was well-balanced otherwise: not overly sweet with a pleasant orange aroma.
Black & Tan
Black & Tan
Ladies and gentlemen, I present to you Black & Tan, the King of Hot Chocolates. Made with 2/3 Medium hot chocolate (which is pretty intense on its own) and 1/3 hot fudge, this is what you order if you want the fudgiest, most intense hot chocolate. Drinking this is more than a little like drinking a hot fudge sundae, so this is definitely one that benefits from a little lightness in the form of the homemade marshmallow. It is also the only one to come in a sensibly-sized tumbler as opposed to a bowl-sized cup like the others.
Medium
Medium
Our waitress told us the Medium is the most popular, and it's easy to see why. Though it may seem like it could be a lightweight—that is to say, low on the chocolate intensity scale—this actually packed a pretty significant chocolate punch, probably thanks to the inclusion of a little dark chocolate and a touch of caramel.
Dark
Dark
The dark was not heavier than the Medium, like we had expected, but it was a little more bitter. This is another one that benefited from the addition of the marshmallow.
Half & Half
Half & Half
Made from equal parts espresso and dark hot chocolate, the Half & Half is definitely made for the coffee-lover. The taste was similar to a mocha, but quite a bit heavier on the espresso than your average mocha.
Mexican
Mexican
The Mexican is a good option if you're feeling just a little adventuresome, but still want the classic hot chocolate taste. The spice is much more subtle in this one than the Chai. As opposed to some Mexican hot chocolates I've tried, it was nowhere near crossing the so-spicy-I-can't-finish-this line.
