This may not be what you had in mind but when I was stuck there for a couple of hours with a
friend about a year ago we discovered that they
sell wonderful fresh fruit juices right there on
the concourse in the airport. We had a bottle of
vodka with us so we spiked a couple of large cups
of juice, sat back and watched the world go by until
they called our flight. It was a pleasant way
to pass the time.
