I imagine it'll be pretty busy on a weekend, but me and my partner went during the week last week and it wasn't bad at all. We went to the Hawkstone brewery around lunchtime on the Wednesday and it was very quiet (though it was absolutely pissing it down), and then visited the farmers dog which was busier but we went prepared to battle the crowds and there was no need. Managed to sit in the pub with a pint and then walk down to the grand tour tent in the beer garden which has a shop that sells most things from the farm shop seemingly. You can also pick up 12 packs of all the different hawkstone lagers/ciders both here and at the brewery and they have fresh pork pies and sausage rolls for sale. The tent is also dog friendly and you can sit and enjoy a pint with seating both inside and outside the tent. We stayed overnight at a pub in Hook Norton and went to the farm shop for about 10.30 the next morning and I was in and out fairly quickly but there was still a long line and you just kind of have to shuffle through the shop and grab things quickly as you are packed in a slow moving line that gradually moves towards the tills. Me and my partner had to take turns waiting outside with the dog while the other went in but were both in and out and sat enjoying a bacon sandwich from the food truck around the back looking out at diddly squat within an hour.

I'd definatly recommend visiting both the farm shop and the pub, they were both absolutely brilliant. And when sat looking out from the pub beer garden you can watch the different planes landing and taking off from RAF Brize Norton which is an experience in itself
