I wouldn’t say Twix is my favourite, but it’s in rotation along with Marathon & Twirl.
Problem with Australia is you don’t get half the bars you do in the UK - so no Toffee Crisp, Yorkie, Lion Bar, Minstrels or the one I have a real soft spot for at the minute… Star Bar.
The only bonus is Whitakers, which is from NZ - nice blocks and their little peanut slabs and Almond Golds are fantastic.
Taking up the Snickers/Marathon thing… I’m still bemoaning the demise of the Texan Bar!!!
