Ireland is a land of drinkers, but not of beerbars.  All of the pubs serve Guinness, Smithwicks, Heineken, Carlsburg, and Budweiser.  A bigger bar will have more towers repeating these same beers.  Really big bars may also have a single tap of Kilkenny, or Beamish, or Coors. The liquor stores in Ireland are similar to those in Maryland, in that they sell wine, liquor, and beer.  A typical beer cooler will have multipacks of the various sizes of bottles and cans of Guinness, Smithwicks, Heineken, Carlsburg, Budweiser, Coors, Miller Lite, and Corona, along with a selection of canned lagers from Eastern Europe.
