Finally, I added a review of Simco's Hot Dogs in Mattapan onto the Boston's Hidden Restaurant site. Simco's is a classic hot dog stand that has been in Mattapan for many decades. They recently opened another one in Roslindale, but to me, the original is the one to go to, as it truly feels like a slice of Americana, with the big ice cream cone sign next to it and its location on Blue Hill Avenue right next to a railroad bridge.
Simco's is one of my favorite places for hot dogs in the Boston area. It's definitely worth checking out!
