There are loads of Irish pubs, magjane. The Guinness is excellent in Spain these days. Occasionally you come across a bar which sells Newcastle Broon too!
I especially recommend a visit to the Estadio Vicente Calderon (Atletico's ground) during your stay as well, so that you can see a footie team in the famous red and white stripes, as worn by the undoubtedly superior neighbours of yours doon the road on Wearside!
