I can't lie. I love Mikado. Any of the three flavours (Dark, Milk and White - you can only get Milk as I write this on Amazon)
The best way you can describe them is like a sweet Jacob's cracker in stick form, covered in chocolate. Alternatively, KP used to do pots of little biscuit sticks with a tiny section of chocolate goo to dip them in. They're like that, but pre-made. Crunchy, biccie a touch bland, but sets off the chocolate perfectly.
But I won't need to tell an anime fan that these things should really be called 'Pocky' :D
