Focusing on serving some of the best pints in all of Dublin, this pub has been a favourite to many locals since opening on Poolbeg Street back in 1854. Known to be a family establishment and one of few pubs in the area that still lacks a television, radio, or other modern distractions, this spot is considered a hidden gem that is instead filled with lots of Irish banter and bolster as soon as you walk in.

To this day, many visitors come to pay homage to James Joyce's story Counterparts, sitting in his favourite perch while being served the house's famous Guinness or a strong shot of whiskey from one of their many friendly staff. Besides Joyce, other significant individuals that have paid a visit include John F. Kennedy, Seamus Heaney, Con Houlihan and even Judy Garland.

The pub is so beloved by many that an entire book was even written on it entitled Mulligan's: Grand Old Pub of Poolbeg Street by Declan Dunne, calling it a "cultural phenomenon" and elaborating on the long history that stems from this famous drinkery.
