As a big fan of milkshakes, I love coming here! The flavors are great, and after having lived in Boston, I really can't gripe about the price. I always order the coffee toffee, and I love that they use both toffee syrup AND toffee pieces. Major points in my book. The milkshake is always very rich.
My only complaint is with the inconsistency of the shakes. Sometimes, you get someone great making them, and other times, they can be less great.
