The catering outlets are only open for breakfast or lunch, which isn't helpful for students who don't live close to campus and wish to stay later into the evening to study or take part in extracurricular activities. It also isn't helpful for students who have lectures over lunchtime into mid-afternoon as everything is usually closed/almost sold out by then.
 

The idea is for at least one catering outlet to stay open so students/staff can get a hot meal around Tea (dinner if you're not northern) time.
