There WAS a Valentine in Columbus at 373 Dublin St. which made Flickr.com, but before anyone could visit this diner, it was found out to have been demolished.
A midwest fan of diners posted this email to roadsideonline.com. It talks about an abandoned Valentine
" The diner is located on the south side of US 24 east of the intersection of CR 232, near 13186 US 24, Cecil, Ohio 45821. The diner has not been in operation as far back as 1975 when I began my career in law enforcement in Paulding County.
