This is the surprise place to bring your French and continental visitors that are riding on the belief and impression that english cuisine does not exist. Play it down, be english and self depracating, sort of i take you to a gastro pub and let the magic of the St John do the hard work.
If you friends are architects, you can mention the following urban myth – what is known – Fergus originally studied architecture before his thoughts turned to cooking. He studied at the Architectural Association – the myth – during his stint there, all his physical architectural models where made up of food stuff – perhaps somebody at the AA told him, go and get cooking – I wonder if this did happen and who was it that say so. A great loss to architecture but such a fine chef.
