As far as I'm aware, few people go to the club nights at the union after the first couple of weeks unless there's a special event (guest DJ, band, comedians etc), people generally go to the clubs in town instead as they're pretty cheap. The pub on campus is more popular, serving a variety of local real ales and ciders as well as the standard selection of drinks. Also they show live sport and host events such as karaoke and pub quiz every week. The jubilee sports centre is huge and well equipped, as well as having a large pool, but you have to be a member to be able to enter. Also on campus are squash and badminton courts that are availablefor any student to book. My halls (Glen Eyre) had their own smaller gym and squash court that requires no membership and is free to use, but I'm not sure about the other halls. On the two main campuses (Highfield and Avenue) there are several different cafes to eat, drink and socialise at, and a shop at Highfield that sells all sorts, as well as a market outside the union every Thursday. If you just want to sit and socialise without spending any money, there are plenty of places indoors and out to do just that, the campus is very beautiful in the sun!
