I'm heading to Dublin soon for a girlie weekend (uni friends - last time we were there together was 1990!!). As I haven't been to Dublin myself for a good 8yrs or so I was wondering if there are any "new" sights, exhibitions, sites of interest nearby that we should check out? Any recommendations welcome

Any particular tips for good eateries in the city centre? Heard there are trams running in the city now...I love riding on the trams here so am interested to use them in Dublin too.
