Temple Bar, Dublin, Ireland -- my favourite city by far! We stayed at the Temple Bar Hotel, with a little grocery store across the street. It's lively on Temple Bar. There's all sorts of pubs filled with live music and people talking.
I will take this advice for when(hopefully) I go to Ireland --> Temple Bar, Dublin. A little further down on the left is an amazing restaurant called Elephant and Castle. If you ever get a chance to visit get their wings!
