I wonder if you have listened to the rules of the game. Briam Turner obviously listens to the guest and cooks accordingly. JC produces dishes that I personally would prefer but he doesn't listen so well.
A few years ago I was a regular customer in a very successful Italian restaurant, regular enough to be able to study the way the brothers ran their business. Much of their evening trade was parties of around 10 or 12 people for many of whom it was their first time of being faced with an Italian menu. So they would take a blind guess and hope.
Shortly after the main course was served Vito would come out of the kitchen and with scarcely a moments hesitation was go straight to the person who he could see was not enjoying. "You don't like that do you", a sheepish "No" would be the reply and he would pull up a chair and talk for a few minutes then take away the plate and shortly afterwards return with something else.
I ate in that restaurant three or four times a week for 14 months and I saw many people who had been treated that way enthusiastically return bringing new customers with them. I believe tat Brian Turner has that sort of talent. It's the way to be successful the first rule of marketing - study your customer!
