The Students Union are pretty good in UCD but I found that you have to make an effort yourself to kind of recognise their presence. The building is down at the bottom of campus next to the sports centre and there are plans in progress to have a new SU building built in a few years. There is a cafe in here which is actually really good, great priced fast food here. They also have a little kiosk where they sell sweets and junk. They have a pharmacy here too which is pretty handy and upstairs there is the doctors so anyone with a problem can just pop up and they can be seen to (although expect a long wait at times!) There's a corridor where the main sabbatical officers are based and during my time at UCD they were always great, although i'm a little biased as some of them were close friends.
