My beer-loving husband was most excited about the Guinness Brewery Tour. All I have to say is wow, the museum is huge -7 floors- and will take you an hour or two to walk through. They even have interactive additions. We went to a tasting and learned the proper way to drink a Guinness beer. At the very top there is a rooftop bar with 360º view of Dublin where you trade in your ticket for a cold one. Sláinte!
