I got trapped at the airport for 18 hours due to delays, etc. One of the only perks I got was a $16 food credit. Not knowing where to go or how much time I had, I walked into Ruby's and ordered a cheeseburger, fries, and drink. All this was over $16, which is nuts, but I only had to pay $1.60 out of pocket, so who am I to complain.
It was a lot of food and pretty decent for an airport. It also came out fairly quickly.
