It's no surprise that people who comment here say that calorie counts make a difference. We are all people who take those things into consideration. However, I can tell you, as someone who owns a quick service food franchise, that calorie counts don't matter as much to the general public. On a daily basis, someone asks me, "How many calories does the ____ have?" (They ask about our most basic, lowest calorie item). I tell them, and they proceed to order something with about 500 MORE calories. I definitely appreciate the laws in California for posting calorie information, it does shape the way that I eat when I eat out, but I know that for most people, the population at large, the postings have not made a difference. I have friends who own chain restaurants also and they have said the same thing, most people don't care. Although, again, being in the food service business, there is nothing funnier than seeing someone order 500-1000 calories and then top it off with a DIET soda. In general, if you walk into any mall food court, the longest lines are at the worst offenders in terms of calories, and people will continue to eat at those places, whether or not the calories are posted.
