About Us

Opened in 2006, this family owned and operated pub epitomizes what an Irish bar should be. Irish owners, managers and staff are the core of the establishment, and coupled with traditional Irish food and drinks, it has established itself as the 'locals' bar located in the heart of Arlington. In 2013, the pub expanded and doubled in size, adding more seating, TV's and a second bar which specializes in whiskey. Now boasting over 130 whiskeys, the new bar and additional dining room hasn't changed the atmosphere of O'Sullivan's, just made it bigger and better. O'Sullivan's loves to cater for events, and with live music 3 nights a week, and Trivia and Karaoke on offer too, it is the perfect spot for a bit of craic agus ceol!
