According to the book "Ballsbridge, Then & Now" by Hugh Oram, this part of Pembroke Street once had the best known restaurant in Ballsbridge, Le Coq Hardi, at the corner of Wellington Road. It was set up in 1977 by John Howard, the first of the celebrity chefs and he ran it for a quarter of a century. It was known for being the home from home of former Taoiseach Charles Haughey. After the building was sold it was taken over by a wine company.
One of the long time residents of Pembroke Road close to Upper Baggot Street was the poet Patrick Kavanagh, who for years had a flat at number 62.
Le Coq Hardi restaurant in Dublin's fashionable Pembroke Road was a symbol of 'Dublin 4' and how the other half lived.
