The criteria for a good hot chocolate changed through the tasting. Personally, I prefer milky hot chocolate but was converted to the thicker variety at a few places. Two conditions were non-negotiable: temperature and taste. The drink had to be hot – not burn the palate off hot, but hot enough to stay warm after the first mouthful. And it had to taste of chocolate. With those two conditions in mind I set out to the best places for hot chocolate in Prague – or at least some of them.
