Davy Byrne's pub is a public house located at 21 Duke Street, Dublin.

[2] It was made famous by its appearance in Chapter 8 ('Lestrygonians') of James Joyce's 1922 modernist novel Ulysses, set on Thursday 16 June 1904.

[3] The main character, advertising canvasser Leopold Bloom, stops at just before 2 pm for a gorgonzola cheese sandwich with mustard and a glass of burgundy while wandering through Dublin.

The pub has since become a pilgrimage point for fans of the novel, who, like Bloom, stop and have a cheese sandwich and a glass of wine.

[2] The pub is particularly popular on Bloomsday, an annual 16 June celebration of both the book and James Joyce.
