My wife and I found this place as we were leaving the farmers market one Saturday, and what a treat it turned out to be. I used to think soft serve ice cream was all the same, but Shakes & Cones takes it to a whole new level. I ordered the BCG (bananas, caramel, and graham crackers) which was fantastic - fresh banana makes SUCH a difference in a dessert. It was just the right amount of sweet and incredibly refreshing.
Definitely worth checking out if you're in Old Town, especially with the weather heating up.
