Covered safe area with plenty of tables, a huge field to park in, (you're better off up the top to avoid getting stuck). There was a burger van last time, and i guess it will be there on sunday as well. Toilets - Yep, and flushing - not chemical.
It got a bit muddy (The paths and stuff, not the fields) last time, but they put straw down which helped.
+ A shanty town of camping students.
