Finding this little folly of a cafe adjacent to the artisan market in Gran Canaria was a joy. I choose a Coffee Bonbon; quite possibly the sweetest drink I've ever drunk! It was simply a single espresso plus condensed milk. Decadent in the extreme. 
I'm not sure if I'll ever have the courage to serve one in London, far too many calories, but surely it's the antidote to all those skinny lattes we're forced to create for the fashionistas and yummy mummies of East London.
