I've been a few times but a while ago (2007-2008). We sought of stuck around Temple Bar but we loved it! I would love to visit the place again soon.
Highlights from the trips:
-Seemingly drunk taxi driver calling everyone "chicken" (including bikers who pulled up alongside: "Hello Chicken!")
-Seemingly drunk taxi driver whom stuck to his word and picked us up at 7am from the hotel 3 days later and even waited half an hour whilst we remembered, thought "oh shit" and promptly got dressed. Seemingly drunk taxi driver wasn't as drunk as he sounded.
-Going to the Guinness Storehouse where once we got to the top, friendly bar dude gave us 2 pints each for "looking like we needed it".
-Seeing the "Guinness Ambulance"!!
-A road trip out to Sligo. Just as we entered the place, I was dying for a pee, so we dashed for the nearest pub. Walked in and distinctly noticed the strange atmosphere (people looking up from their newspapers, others stopping talking). "Uh Oh" we thought. We ended up having a few pints chatting to the locals asking where we're from etc.
