Servers who bend over backward to make your meal a pleasant experience can add a half star to a rating. When a place earns 4 stars, you can expect a superior dining experience. Imagination is an important part of a 4-star meal if the emphasis is on modern in food and decor. But a traditional restaurant can earn the same rating when everything is in its place and when you look at the check you feel that the price is fair. You want to come back for more above-average food and service.
Food has to be superb, just as good as the service.
Only a couple of minor mistakes can be tolerated at this level. And crumbing the table before desserts is a must. When the server pulls out m'lady's chair, spreads a thick white linen napkin gently over your lap and knows as much about the preparation of the food as does the chef, and when you have a flawless meal that you will be sure to tell your grandchildren about, you're in a 5-star restaurant.
