We have eaten in a lot of places with Chef's names over the door, never a sign of the Chef and even the Chef's in the restaurant have never met the main man.
Jamie Oliver has restaurants all over the place. He opened one in Aberdeen, but was not there. A friend of ours and her husband had dinner there, they said it was expensive and the portions where very small. In fact after their dinner they went to the Fish and Chip shop for a carry out.
One of the Roux Bros has his name in an Hotel in Inverness, again, we have stayed a number of times as have our children. Never seen him once.
I personally think that putting a famous name over the door is a great excuse to increase prices.
Also, I realise the restaurant is not in Calis, but as this is the Calis Beach Forum a lot of people from Calis will read it.
Anyway, I happen to know all the restaurants in the Calis area have a Chef straight from Istanbul
