I'm wildly impressed by this terminal. Having become a Las Vegas resident, I travel through this airport a lot. My least favorite time to fly out are Sunday mornings. It's the busiest time and there is usually a line outside, wrapped around the building. My favorite time to fly in are Sunday nights. So. Many. Casualties. You literally see it all.
The security is quick though. Some days I'm through in 5 minutes, compared to 30 minutes at Terminal 2. When it's packed they usually bring out the security dogs to keep things moving.
Now, the food scene here isn't ideal. But they have a Jamba Juice, Coffee Bean, & Jersey Mike's Subs. Plus you can take your cocktails Togo throughout the airport. What more could you ask for?
