There used to be a restaurant in Merion Station, PA called the General Wayne Inn which was considered the oldest continuously-operating restaurant in the US from 1704 until it closed in 2002. I was trying to remember when it closed so last night I googled it and fell deep into the rabbit hole of reading about the supposed ghosts and very real murder that occurred there. Apparently there was a 1988 Unsolved Mysteries about the ghosts, and in 1996 the murder story was on America’s Most Wanted. (Don’t be an idiot like me and read about it right before bedtime!) My husband’s grandfather did some plumbing for them back in the day and allegedly saw the Hessian ghost. He said the ghost said “Can you see me?” in a surprised way and then his grandfather left in a hurry.
Anyway, it’s not on the list since it’s not still a restaurant (it’s now a synagogue) but it will probably always be the oldest restaurant I’ll have eaten in.
