technokc,
I'm Irish, allow me to explain to you how to find a good pub in Dublin (my home city).
Dublin is a thousand-year-old city which grew out of a small Viking settlement. As a result the street layout is rather meandering and criss-crossed with narrow alleyways.
Should you (or any tourist) find yourself on a Dublin street you should proceed immediately a hundred yards in any direction... this will bring you to a what we in Ireland lovingly refer to as a street corner; there you will find a pub and/or nightclub. In the extremely unlikely event that this course of action fails immediately institute your back-up plan by glancing across the street... there on the opposite street corner you will find a pub and/or nightclub.
Should you (or any other tourist) find yourself on a Dublin street and unable to walk a hundred yards then simply rotate in position to identify the location of the nearest pub and/or nightclub situated between street corners. In some parts of Dublin this may entail walking the length of several shopfronts, so plan ahead and bring supplies.
Good luck. (You won't really need it though, Ireland has a pub for every 3,000 people which is the highest ratio of any country in the world. In Dublin the average distance between licensed premises is about 100 metres... translating to a dozen pubs per street in the city centre)
