Okay, the place has been around quite a while, the person who owns it now is third or fourth generation of the same family that bought the place. You can see signs of the age, the restaurant is a medium sized place, could be considered "cozy." The walls are littered with various things, mostly license plates signed by some customers, pictures of people with cars.
The owner's name is Nan, she is known to be the one to go to for gossip about the small town. She knows about the Winchesters and the hunting, as well as the Academy, and will take it to her grave - because they had helped her family once.
It is open 24 hours, it is also a truck stop along the highway.
