It's great here. Come visit!

The best we've had were in Granada, but Madrid does them pretty well too.

I've had a look in the shops here to work out how to make it at home. They seem to have some fairly expensive stuff which is already liquid and I guess you just warm it up, some ordinary looking cocoa powder, and lots of Nesquick.

I now have another excuse to do soem more investigating, or ask someone, and work out IF it is doable on a normal stove.
