I've been here like three times this year and I'm constantly surprised at how quickly security moves. The only thing I don't like is having to go through security and then having to take the train to the gates. It does come pretty fast though and I guess saves you a long-ass walk. The mall in here is great, has a wide range of shops and "fast food" such as Clinique, Victoria's Secret, Sunglass Hut, Rite Aid, and I usually grab a sandwich from Au Bon Pain and take it on the plane with me.
Bonus: No sales tax on clothing. What more can I say?
