The Ohio House Coffee Shop is located in the Ohio House Motel and opened 53 years ago.
The owner says he will be replacing the diner with a franchise store, but the motel is not closing.
Long-time customers say they'll miss the family atmosphere and the diner's home cooking.
The shop's owner says he has no plans to move the diner elsewhere.
Customers say if he opens another shop, they'll be there opening day.
