this is mainly for those living across the pond or to those who have visited before, but i'm vacationing in ireland and britain in a couple months and am hoping to drink some of the finest beers these countries have to offer. i've had a lot of the stuff they export over here and enjoyed most of it (guinness, fullers, youngs, samuel smiths, st peters) but i'd like to try some quality brews that aren't available in the states. any suggestions? also if you know of any good pubs to check out that would be a bonus i'm not 100% sure where i'll be yet i know london, shannon, and dublin for sure... it will be mainly southern ireland. cheers!
