Toblerone is good chocolate but crappy design
The shape of is needlessly efficient for transport and storage. It is awkward to eat. The only way to snap a piece off is to grab it, smearing chocolate all over your hands, since the base is usually too thick to snap cleanly and easily.
The triangle shape just makes it awkward to get the mouth around. The base is too thick, such that it nearly breaks the teeth biting through it if it is remotely chilled/hard.
I'd rather just have the same chocolate in the standard bar form.
