Stopped here for a double expresso while waiting 6 hours for my delayed flight. Had a $24.00 food voucher from my airline. Anthony and his female colleague were really helpful. They told me I had to buy $24.00 of stuff all at once and suggested it might be better to go to a restaurant - as I'd have to buy lots of stuff (I was alone) to get to $24.00 total with them.
So, I decided to just buy my expresso, but I was really impressed with their friendliness and helpfulness, especially at an airport place, where customer service isn't always the best. It was a good experience and good expresso.
