We popped into Caffe Nero and saw their festive menu contains salted caramel which can be combined with coffee too.
We are in complete agreement that Cafe Nerro serve the best hot chocolate (delicious and generous with the cream) on the high street. We were excited to try their festive offering. The medium was £3.40, we got a large of course.
It was delicious up until a point, but then the congealed camerally syrup caught up with us and it became a bit nasty and sickly.
For a standard hot chocolate Nerro is king of the high street, for a christmassy one, it is not.
