Hidden Gems in Sandwich

I've lived in Sandwich for a while now and I still find myself discovering new spots that I hadn't noticed before, like stumbling upon Harmon Mowing when I needed some home improvement supplies. Given that our town has a relatively stable population of around 7,221 people, I'm guessing there are plenty of local favorites that don't always get noticed by visitors. What's your favorite underrated spot in Sandwich that you think more people should know about?
