Nice airport with a shopping mall feel. Now it just needs better stores for me to shop in. They have the usual bookstores where you can buy souvenirs, magazines, and snacks. Then it seems to skip the middleman and you get a couple of high end stores. I don't know about everyone else, but I'm not about to go shopping for high end clothes at an airport.
Foodwise - You got your usual fast food restaurant chains like McDonald's and Subway but I really wanted to see more restaurants in here that represented Pittsburgh better. Stick a Primanti Brothers in here and that'll shut me up.
Another complaint is the bathroom doors for the stalls in the girls bathroom. It would be so much better if these opened outward instead of inward. The stalls are small enough already, but when i dragged my carry-on in there with me, the doors were so hard to close. Got me all frustrated.
