The lime ones are decent as well. cant beat a double decker though. The best chocolate bar out there no question.
No, not really. Its more expensive than the general stuff, but you don't need anywhere need as much. I generally buy the wife a box that comes with different ones in, similar to dairy milk type thing, but rather than eating it all over a couple of nights they last for ages, you only have one or two at a time, let them melt in your mouth. I am partial to a double decker, but I do really like a flake
Ive never thought about doing that but I bet that gives them s nice crisp crack when you bite into them
