O'Neill's is one of Dublin's grandest Victorian pubs, occupying a sprawling building on Suffolk Street with multiple bars over several levels, each with a different character — from a lively ground-floor bar to quieter snug areas upstairs. The ornate wooden fittings, stained glass, and tiled floors are original and impressive.
The pub serves reliable Irish bar food and hosts live music most evenings. Its location a two-minute walk from Trinity's front gates makes it popular with students, and the size means it rarely feels too crowded even when busy. A good choice for a first Irish pub experience.
