I would hate like hell to see nutrition info be mandatory - there've been numerous studies I've seen (and yeah, a study can be skewed to give any kind of result) that making the info available and easily accessible doesn't make a difference to the majority of people....
I disagree about the nutritional labels. I think they need to be mandatory everywhere possible. For example, I just saw today that the cheese fries at Outback were something like 2,900 calories and 185 fat grams. I bet some people would have no idea how bad it is.
