My favourite is chocolate fudge, very nice indeed
Then mint - I LOVE mint chocolate, but I can't really get overly excited about it.
Coconut was ok. My brother described it as 'if you forgot it had coconut, it just tastes like a normal KitKat'.
I thought the hazelnut was disgusting. FAR too sweet and I couldn't even finish one 'chunk'. Even the thought of it makes me feel a bit queasy now!
