There is a decent bus system, but I didn't use it because I didn't go too far from Temple Bar. The Porterhouse is a microbrewery, and they have plenty of beer to choose from, but I don't remember being able to bring any home. I'm sure that somewhere in Temple Bar there will be a store that sells beer in bottles. I recommend Brew Dog 5 AM Saint, Punk IPA, and Hops Kill. Oh, and if you can find beers from the Cairngorm or Salopian breweries, those are great too...and you've gotta try Hobgoblin or Black Sheep Ale. Deuchars IPA isn't bad either. Those are all UK beers, and Ireland isn't in the UK, but I imagine they'd still carry a lot of the English/Scottish stuff.
