Derry has a lot of bars, and many provide some kind of entertainment at night. A good way to find out about what's happening is to head to the nearest newsagent and buy the 'Derry Journal' (also affectionately known as the 'Derry Liar' amongst the locals, out every Tuesday and Friday). Check the Entertainment pages. There's not just venue listings for Derry, but also many places in Letterkenny and Inishowen. Also look around when you're walking through the city, there's posters everywhere advertising most gigs and club nights.
