Decent selection and clearance pricing can be found at the Brooks Brothers store. Once you're done shopping and still have some time to kill before catching your flight, you can rest your bottom on one of the dozens of white rocking chairs that line the atrium. The rocking chairs are a nice perk and you should definitely try to take advantage of them if you can.
The only complaint I have are with the transport carts. They are constantly beeping no matter what direction they're going. I can understand the beeping while in reverse, but it's really annoying when it's constant. Especially when you have 40 minutes to kill at the gate.
Thank goodness for the free WiFi...
