There are places to sit, eat, and work, on both sides of the security checkpoints. It's a great place to work from, when you have time to spare before catching a flight or meeting an arriving passenger, etc. Outlets and wifi vary from shop to shop and all waiting areas. Rogue Brewery has great standing bar strip along windows with solid WiFi connection and power. There's a decent wi-fi signal in the Baggage Claim area, too. The building is gernerally open 24 h/day, and there's a 24-hour store on-site. However, most shops and restaurants close at around 9 - 11 pm. Security checkpoints closed from 1:00 - 4:00 am.
