I'm glad they're always upgrading and adding more places to eat / drink. The lines are still overly long and slightly inefficient, but if you arrive an hour early you're ok.
Staff is very friendly so if you're in a rush, they can help expedite you forward.
I wish they had more charging / power adapter stations. Everyone in Vegas is down on battery and needs the juice.
They have free WiFi too! And slot machines (might be only airport in America with it). Though they should really ban smoking rooms (that ish is nasty and it's no longer 1907).
