@Lordyaswas,
No - it's not filter coffee you heathen - it's a shot of espresso with a mixture of hot water and hot milk - so a more watery latte.
Stupid thing is I never order a flat white. The lady gave it to me buy mistake. I used to be a regular vanilla latte drinker but gave up coffee last christmas, and now, maybe once a week, get a chai latte.
It was actually nice without the vanilla, but she gave it to me for free when she realised her mistake. (It's so weird - I never ask for anything because I always get the same thing and the staff at the student run cafe know me - so they just hand me my regular - exam period has fried everyones' brains).
