There are four bars in a row on Union Quay(which is, as you would expect, on the river). The Lobby has a fine array of musical events in the trad line, both guests you pay for upstairs, and sessions downstairs. In Charlie's next door on a Monday night you'll hear Ray Barron and Hank Weddell, and unmissable experience in an amazing bar. Asking around in either of those bars will soon let you know whats going on in Cork.
