Suntan12 - I think that it is a good idea but I know that the restaurant industry would fight it because they would not want you to know how many calories and fat is laden in their meals.
Most people that go to a restaurant go to enjoy the food, but if they had this information restaurants know that many people would make different choices and they may exclude their restaurant from future consideration because the food is so fattening. This is why McDonald's offers its nutritional information on the bottom of a placemat when you would never notice it.
I know that everything in moderation is okay, but I feel so guilty eating something that I know is so bad for me that I would probably be one of those people that would not return to the restaurant if I knew how the foods were prepared.
I do feel better when I see that a food is transfat free, but I always double check the ingredients because much of the processed foods do still use traces of transfat.
