Guinness Storehouse is the top Dublin attraction and for good reason it has a little for everybody (of drinking age)! Music multiple bars and food made with Guinness (very common thing in Ireland). It is a museum but more MoMA than MET, contemporary with pieces of his old and contemporary history. I had a blast even if I was there by myself. Suggestion get there early and/or get your ticket to cut the line. If you did a Redbus Tour or got your ticket that official Tourist center is free. The best part of the experience was getting the chance to pour your own Guinness pint and get your picture taken. https://www.guinness-storehouse.com/en
