I'll give up my food, I just hate that you can't bring your own on without spending another $15!
We were in the Kansas City airport this weekend. It is long ans skinny, so all of the food is on one side, with security right in front of your gate. There is not an option for purchasing food in the "secured area" with the exception of vending machine junk. I paid $7 for my Starbucks and couldn't even drink it all!
In most of the small airports the selection in the "secured area" is terrible and outrageously priced. FI's personal pepperoni pizza from California Pizza Kitchen in St. Louis was $11.99!
