The Dirty Onion

Situated in the heart of Belfast’s vibrant Cathedral Quarter on Hill Street, The Dirty Onion is one of Northern Ireland’s most characterful and historic social institutions. Housed within a lovingly restored 1751 timber-framed warehouse—believed to be the oldest surviving building of its kind in Belfast—the venue blends deep architectural heritage with a boisterous contemporary pub and live music ethos.

The venue features a massive, multi-level heated outdoor beer garden wrapped in authentic wooden beams and stone arches, centered around an open-air fire pit. Inside, rustic wood-paneled bars and peat fireplaces create an atmospheric backdrop for enjoying craft beers, local ciders, and a vast collection of Irish whiskeys alongside chicken rotisserie dining from Yardbird upstairs.

Live music is the heartbeat of The Dirty Onion, featuring acoustic folk, traditional Irish sessions, and energetic rock performances seven nights a week with no cover charge. Packed nightly with locals, students, and international travelers, The Dirty Onion represents the irrepressible, welcoming soul of Belfast’s nighttime scene.
