DFW is our main AC and we wouldn't trade our membership there for anything! As someone else said... a place to escape the gate mobs, plenty of places to sit and relax, internet, spiffy bathrooms, and yes, even snacks of some sort of another (these change all day long at DFW starting with Breakfast bars which we love, then Apple, afternoon cookies, celery and Ranch, cheese and crackers.
Granted, it's not anything we can hardly wait to snack on, but it's there if we need it. A lot of the time, we go through at noon and are quite happy to order a sandwich from the bar. The Hot Cuban Sandwich is outstanding.
The only thing I don't like is no regular Lay's potato chips. Why they only have tasteless baked, I have no idea!
