He returned to New York from his home in Florida this month and was hospitalized last week.
O’Neill's first opened in 1933, and was known for its philanthropic activities. The restaurant hosted numerous fundraisers, including raising money for St. Jude Children's Hospital.
Every Christmas, O'Neill hosted a holiday party for the NYPD Honor Legion, which is dedicated to children and family members who lost a loved one in the line of duty.
Following a fire in May of 2011, O’Neill's rebuilt, and recently received support from the community to expand with a second-floor catering hall.
