The Guinness Storehouse in Dublin is amazing!
Ian and I got to learn how to fill the glass with Guinness stout properly (and we get to drink it). The ones there taste so much better than those I tried in Sg and I actually liked it. A lot.
Also, love the river reflection of people on the bridge. Looks as though they are in the water; really cool. Also, the sunrise/sunset in UK/Europe/that part of the world never fails to amaze.
