As above can be a mare parking.
If its a hunugry horse your after

and search within oxford.
Been to the tandem in kennington no complaints there great service but car park potential problem if busy, awful service at hungry horse one on way into wallingford
When i had the focus we used to use the pub the turnpike IIRC just off a roundabout the oxford end on the A44 to woodstock you'll know it.
i'd go for turnpike. not too far away either just off A34.
depends where majority are based.
Other suggestion hows bout sturdy's castle just past kidlington on old road to banbury.
