Madeline and her husband, William Wong, opened the restaurant on Route 1 in 1959 and grew it into a landmark establishment over the next six decades, WCVB reported. William died in 2011 at 88 years old.
The couple had six children, several grandchildren, and great-grandchildren who run the restaurant today.
The family did not release any information on her cause of death.
Those who knew Madeline Wong remember her as a tenacious businesswoman and loving mother with a big heart.
"I just look at her as she's a superwoman. A pioneer. A loving wife to my dad for 62 years," her son Andy Wong told WCVB earlier this year. "She always had love for everybody."
