Finally went here to try the Frozen Hot Chocolate so I could compare it to Serendipities (see their review). Was only about 2.00 and tasted pretty much the same as the one at Serendipity. Don't waste your money at Serendipity. I also figured out the difference between a Chocolate milkshake and a frozen hot chocolate: The milk shake is made with milk, the frozen hot chocolate is not, its just ice and chocolate mix kinda like a chocolate slush. That's why you get more chocolate flavor in the Frozen Hot Chocolate.
Anyways, now about this Dunkin.... the service was not very friendly. Additionally, we came here around 1:00 on a Sunday and ordered some doughnuts along with the Frozen Hot Chocolate. Needless to say, the doughnuts were not fresh in the slightest. The hubby said they tasted like they had been sitting around since the day before. Needless to say, I was not very impressed and would rather go to Krispy Kreme for doughnuts and if I ever want coffee, I already know that Dutch Brothers is the best with really friendly service as well.
