Flat white is what I've asked for as a coffee for years, particularly in London. (Down here I seem to drink Americano with semi skimmed milk).
And now Costa have launched a drink called Flat White; which is made of frothed milk just sort of flattened down and horror of horrors full fat milk.
Gutted. It's not my drink anymore. Not only do I hate full fat milk I'm distinctly unkeen on things that have been frothed; even then flattened I'm not keen.
