I like them best in winter, so I can heat them up (though I admit, it tastes better cold). A cup of cream soda with a couple teaspoons of sugar and a dash of cinnamon--gives it a kick and makes it foam more.
It was a hit at the Halloween Banquest my HP Club threw back in high school. I let my teacher (who went by "Sirius") taste it and he immediately said, "Hey, this is butterbeer!!"
