As suggested by one of our members, I've booked us a table at The Hornbeam Cafe's Seasonal Supper club.
It is described in their publicity as 'a feast with delicious healthy tasty food - locally sown, grown, picked and cooked!' and it costs £15 for a 3 course vegetarian meal. Drinks are extra and you'll need to bring cash.

Please only sign up if you can commit to coming as it is a small venue and places are limited. They also need to know how many people to cater for.
