There are two entities here worth reviewing: the ice cream palor and the candy shop. Both are excellent, and I have driven from Pittsburgh to Canonsburg just for the milk shakes
The ice cream shop is old fashioned and excellent. The milk shakes are huge, but well done. In fact, it's probably the best ice cream shop I've ever been to. Good ingredients all around.
The candy shop is also excellent. The peanut butter meltaways rock. They get all Christmased out during the holiday season, and have custom chocolates for your family (like a doctor set, or a hockey puck & stick set). The prices are good and the chocolate is very good.
