It depends on how much you want to spend...
Fairly expensive, Randolph, in Oxford itself and the old parsonage, then the Feathers and Bear in Woodstock,
I liked the Bear and Ragged Staff in Cumnor for more formal taking elderlies out to lunch..
The perch in binsey is nice, I think, or it was, ditto the trout at Godstow and the white hart at wytham, I haven't checked for numbers. ,
A little further out still, look at The Bell in Charlbury, haven't been there for years, but was ok then.
What used to be the four pillars and us now I think called the Oxford spires is fairly standard
Then there's Raymond Blanc's Manoir...
