Jack’s Diner owner to reopen Downtown restaurant after wife’s death

Jack’s Diner, a landmark greasy spoon in the heart of Downtown since Jack Holt opened his namesake in 1942, has been closed for almost a year. But last Thursday, a security guard on his lunch break looked inside and got the news that Chris Kowalski’s loyal customers have been seeking. “Yeah, I’m going to reopen soon,” Kowalski said with a wide grin.
