On balance, I’m in favour of this product.

Not the other sorts, just this one.
I visited a takeaway shake place in Oxford the other day called, um, er, “Shakeaway” – they did a Toblerone milkshake, amongst many others. I was mildly impressed but on reflection I’ll stick to solids. They’re worth a visit, though, should you ever find yourself in Oxford. Whither a Parma Violets shake?
