In the inconceivable event that there isn’t one near by, you can make the home version.
Grind charcoal briquets, make your beverage with them instead of coffee grounds (or no less than a 50% mixture of briquets and cheap ground coffee).
Mix with large amounts of flavored syrup and cream, cover with a layer of foamy scum, scratch some fancy pattern in the scum.
Enjoy.
Hahahaha! That’s spot on.
