Various groups of locals put their aprons on and sell cooked breakfasts every morning, raising money for charity. Please support them.
There are good pubs and shops in Cropredy where you can buy meals or supplies. However, they get very crowded, so be prepared to queue. It's a good idea to have at least some snacks or simple meals at the tent. Keep food in a plastic box, lidded if possible, to keep out bugs and damp.
There's an international cornucopia of take-away food available on the main music field itself, ranging from fish and chips to Chinese, Indian, Aussie steak sandwiches and doughnuts to the wonderful Leon's vegetarian stall (www.leonlewis.co.uk) - food so good that many consider it to be as important a part of the Cropredy experience as a pint of Wadworths 6X and singing Meet On The Ledge with 20,000 people at 11.55pm on Saturday night!
And there's the bar (www.wadworth.co.uk/)! Huge, manned by an army of friendly staff and serving everything you could ever want (as long as all you want is beer or cider). However, if the weather is hot it's a bright idea to make sure you have plenty of bottled water with you. Beer just won't do the job of stopping you from dehydrating if the temperatures get silly, as they have been known to!
Parents should take provisions for their hoards in the shape of fizzy pop, water etc, as this can be expensive on the field.
Should you need to do so, you can always drive off the camping fields to get supplies from Banbury, where there are large supermarkets, camping shops etc. The camp site marshalls ensure that access lanes are left between the rows of cars/tents so getting off and on site is no problem.
