I never ate at Hartman's Steak House, but it came across my radar when I was researching Durham's oldest continuously operating restaurant for my post about Bullock's - I thought perhaps it was the winner, having opened in 1941 (two years before Bullock's) but soon realized that it closed in 2001, at its 60 year mark.
(From the 4/26/53 Morning Herald.)
The building has sat empty since that time.
Former location of Hartman's, 10.10.10
Local non-profit TROSA acquired the property in 2011.
