My local paper reports that a law took effect in Westchester last week requiring chain restaurants to include calorie counts on menus. The idea apparently is the law will induce fat people to eat less and lose weight. I don't think this is very likely.
On the other hand the law will help people like me who see food as fuel get the best deal for our dollars. Although the law doesn't appear to apply to the restaurants I patronize most as they aren't chains.
