I have low expectation of airport food, too, but unless you get a direct flight at the right time you're going to find yourself needing to eat at an airport.

The section I was in had some automated sandwich kiosk and a burrito joint that had a huge line that wasn't moving. Walked to another section that had a Shake Shack and some kind of pizza place. Ordering at Shake Shack was fine but it took about 20 minutes to get my order. On the plus side there was an old guy who was also waiting and telling the dirtiest jokes to anyone that would listen.
