Camp site kebabs are filth. That is unless you like eating dog hair.
I don't know of any good places to eat near the curcuit, you may need to go into town, but be prepared to queue. I reckon the best advice is to take a proper stove and get one of your birds to knock up a chilly, curry or spag bol, all sauces from a jar of course. You can chuck in a few veg, meat etc. Fit for a King!
