Driving on Easley Bridge Rd just west of Greenville you will find two restaurants next door to each other. They basically share a parking lot they are so close together. They are both "CLOCK" restaurants. The first is Clock Drive In #5 and the other is the Clock Family Restaurant.
I've heard two stories about how this came to be. Both versions agree that the Clock Drive In #5 was first. It opened approximately 1987. Story one says that the business was family owned and during an argument the family broke up with one side opening a competing restaurant adjacent to the original.
The second version of the story says that the brothers that owned Clock #5 were leasing and had a falling out with the land owner. So approximately 1996 they purchased the adjacent lot and started another Clock restaurant. Clock #5 was purchased by new owners and remains in operation.
I did some brief Google searching yesterday and couldn't find any hard evidence on either story but I do know this. Both of their signs advertise nearly identical items and the decor of the restaurants is very similar. Leading me to believe that there is some relation and history between the two and they use their signs to continually take jabs at one another by mimicking.
