This Cayce home cooking restaurant was at the corner of State & Jansen Streets, right across from Brookland Cayce High School, and right next to the old radio station studio. As you can tell, these pictures were taken on a very grey and gloomy day, otherwise the old brick building would look much more inviting.
I know for a while they advertised themselves online as either the follow-on or alternative operation to the old Southern Skillet when that restaurant closed.
In the event I had never heard of them until quite recently, and never got around to checking them out until it was too late.
