I wonder if Nestlé has made any changes to the formula (i.e. different chocolate etc) for the American market. It's long been a practice for many candy companies (such as Mars, Cadbury) to offer the same chocolate bars (what Canadians call candy bars) in the US and Canadian markets with darker/sweeter etc chocolate.
Nevertheless, Coffee Crisp IS a nice, light snack and one of my faves!
