Superquinn is now the grand daddy of Irish supermarkets. There aren't too many of them; you'll find another branch in Swords, Co. Dublin as well as several other locations outside Dublin. Tesco, the British supermarket chain, bought out an old relation, but Superquinn remains a popular place to shop. A full selection is available from basics to truly gourmet ingredients and extras. If they don't have what you're looking for here, it is probably not easily available in Dublin.
