I'm in North Oxfordshire, often in Banbury. Reasonably well placed for Lotusbits and Paul Mattys.
Haven't been out for a curry for a while, good selection in Parsons Street in Banbury, also the one in the centre of Kidlington.
Nearest Club Lotus group is the BBOA (Bucks, Berks, Oxon Area), they have monthly meets near Jn 3 of the M40.
Try the Warwick to Banbury road B4100 road, runs parallel to the M40.
The Motor museum at Gaydon is also on that road.
