The Grauniad published a list of its recommendations, De Barras gets a deserved mention. http://www.theguardian.com/travel/2014/mar/17/ireland-best-pubs-music-bars-dublin-belfast I'm sure Chris M could add a few to the list.
Not wanting to do an "andi" and post something completely un-related, so it is an Irish themed reply - but Dave - are you going to see Luka Bloom at the Purcell Room on 7/11/14 ? Just bought a couple of priority tickets which are on sale today; probably the last chance I'll have of buying such tickets, as my membership runs out in May. I only buy membership to buy Roy tickets and thus don't think I'll be needing it in the near future !!
