What is your favorite airport?

It is a pretty unusual question to ask but I am curious! I remember that one time I was traveling to the US and we had to stay in Moscow overnight due to a canceled flight. They paid for the hotel but because it was a full board, they gave us money to buy some food but because the ruble was worth so little, we were able to buy a high quality meal in Domodedovo airport. Also, the airport didn't close for a single second and we were able to stay in it without having to pass security again. Also, the free unlimited public wi-fi really helped us because we were overseas and didn't have cellular data.
