Dublin, her river Liffey, from which Guiness is produced, her pubs... Trust me, if you go in Dublin with some friends, you should try some pubs. If you don't have any friends, and if you're not too dumb or annoying, go to a youth hostel (Isaacs hostel is fine), speak to some people, and go to Temple bar. Gogarty's is fine, you would find on the first floor traditionnal music, and on the ground floor, more recent american tubes. Great to flirt, Yann told me.
Temple bar is not only a good block to get drunk, it is also a good pub... And you would meet a lot of people there. We met some french people (again, just to keep a good level in french, I assume). We went to another pub where we listened to 70's rock music (don't remember the name of the pub... I'll tell you later, if I can recall it), to some other places... It was really fun!
So, I hung around with french, german, ostrian, italian and american people... Again, that was really cool!
And according to an ostrian dude, I don't have any french accent... Of course, that was compared to Yann's accent. But still... He was the first guy not to guess the place from which I was after he had listenned to me.
We went to a pub where we were told that was a nice place to meet other young guys, but when we arrived (around 11:30pm), there was just more old dudes (like in their 40 or 50) than 20 and 30... Anyway, there was still rock music, and we had a good time.
