Ossian Smyth TD has compiled a list of Dalkey businesses that are offering full or partial service during the COVID-19 restrictions. http://www.ossiansmyth.ie/local-business-directory/#Dalkey
There is also an app that was recently designed in Dalkey. It lists small and medium businesses that are ready to bring food to your home or organise a pick up. http://www.atyourdoorstep.ie and choose location ‘Dalkey’.
