According to a statement from the café, Mr Coia passed away peacefully on the morning of the 31st of December.
The Coia family opened their first café in Dennistoun in 1928, with Nicky Coia and his wife Ena taking over the business in the 1950s before passing on ownership to son Alfredo and his wife Antonia Coia in the 1980s.
Staff said Mr Coia continued to be a regular face around the place and still "enjoyed being involved".
They added that they know many of the café's customers will have "great memories of Nicky".
