damn good. in my fridge I've got a pound of what I'm told is the finest imported espresso grind you can get in NYC that is (supposedly) only available at this one Italian joint in south Brooklyn. and it really is superfly espresso. it's great because I have to stay awake until around this time tomorrow. anyway, my point is that a lot of people pronounce it "expresso" and that's not the correct pronunciation.
i finally got an espresso machine and i'm in love with it it's not as powerful as the commercial one i used at my old job but it's still mmmmmmm cappuccinos
it REALLY grates on my nerves. not even so much because it's incorrect, but because it's even spelled phonetically. "hey nick, do you want to come to breakfast with me and your cousin? they make a hell of an expresso at that place!" "sure mum... but, er, it's pronounced 'espresso'"
