Brunel is split into four sites and each needs to be considered independently.
Uxbridge
This is the University's main site and thus has the best facilities. The Academy is the on-site venue where it all happens and comprises two floors. Downstairs is the main SU function area. Due to its capacity (600-1000) and the 2300 students at Uxbridge, it is packed just about every night. Upstairs there is the Bishop's Bar which is more for sports players but is good for a relaxing drink.
Twickenham and Osterley
Although these are seperate sites they can be considered together. Somewhat worryingly the uni has closed all the SU facilities at both these campuses so it's local bars only. They are intending to centralise everything at Uxbridge and this is a step in that direction. Doesn't do a great deal for the students there now though does it? Osterley is Brunel's sports campus and is very very serious about it. This does mean a particular atmosphere and there are some interesting events. The most notable was a 3000 signature local petition to ban Wednesday night drinking due to students going on the rampage when drunk after matches. Apparently damage to garden gnomes alone totalled several thousand pounds.
Runnymede
This is the smallest of all four sites and has very poor facilities. A small bar is all you will get. Most students here take advantage of the facilities at nearby Royal Holloway. These are excellent. There have been problems in the past from this arrangement resulting in Holloway banning Brunel students on more than one occasion. It would be nice to say that both colleges students were at fault but on the majority of occasions the blame has been laid squarely at Brunel, meaning that a greater degree of care and attention is required. A close cooperation between the two unions has minimised this problem though.
