Pocky is a snack made by Glico here in Osaka, a cookie stick dipped in chocolate. It's really, really popular in Japan, and is sold in a number of other countries too. When in Paris last summer we found "Mikado", apparently Pocky by another name. We had to compare.
Both are made by Glico. The Mikado stick is a bit shorter, and the taste was a little different - but we got milk chocolate Mikado, and dark chocolate Pocky so that's no surprise. The cookie seems to be the same. If you get a Pocky craving in France, you can safely look for a Mikado box and rest assured that you're getting the real thing.
