Wonderful views over the Warwickshire countryside (ring and reserve a table in the window if you can). Varied menu and you may spot to occasionally internationally famous film star in there (we saw Mark Rylance in there last year). Also do afternoon tea. Huge outdoor dining area and open air movie nights in the summer (check their website for dates).
