There's clohessy's bar on harvey's quay by the river - that stays open til after 2 and there's the sinbin niteclub connected to it. And then there's 3 late bars on denmark street - just off cruises street - Nancy's is probably the best one. Flannery's and Smyths are also there.
If you're looking for something a bit different - as in a bit of a s**t hole but a good craic - there's Costelloe's in Perry Square that stays open till late. It's just off Glentworth Street longside Taits clock.
