Just got finished watching "Kitchen Nightmares". I have started to become a very big Gordon Ramsey fan!
One of the things that he seems to emphasize is one having a passion for food! Especially when its one of the chefs!
He goes to a restaurant whose business is not doing well and tries to help the business get better - which in every case he has seemed to do!
It always seems to come to the food itself. Serve good food to the customers and the word (and your restaurant's reputation) will spread!
