I have used Chicago O'Hare numerous times for International and Domestic flights. I wanted to give this airport 4 or even 5 stars for the experience I have had of Terminals 1-3 however T5 drags it right back down. Departures: There are almost no facilities beyond security bar a few carts selling candy and cigarettes. There is no bar except for a temporary stand selling bottled beer - not exactly the way to unwind before a long flight. Before security things are a little better - you can at least get something to eat albeit at McDonalds. Arrivals: There's a long wait for bags however my destination has always been from Ireland where immigration is done before take-off so this mitigates that somewhat as we don't have to queue. There is a bar in arrivals (one might have considered putting the bar in departures?) and a shop but little else and the area is cramped with few seats. The rest of O'Hare is a pleasure but it's as if International flights are an afterthought. I understand that Chicago is a domestic hub but as an international traveller it's actually a bit of an insult.
