I have frequently dropped into the Natural Bread shop in Oxford and enjoyed being welcomed by the staff for delicious food freshly cooked in the kitchen there, and I have in the last two years tried nearly all the different sourdough breads of there of stunning quality.
If you really want quality fresh bread do head Little Clarendon Street shop. My favorite is "Spelt", The croissants are great and also the pain aux raisins. Good luck to you all and thank you for your dedication particularly to quality bread. JAC
