Note: I have Celiac disease so I can’t eat gluten.
I used the Find Me Gluten Free app to look for a safe meal option at the airport, and was baffled with the amount of reviews of people getting sick from the restaurant options in the terminal I was at (Terminal T). Thankfully, Terminal A is right next door and with a slight flight delay I was able to hop over to Shake Shack as that seemed like the safest place based on reviews (PF Changs is also in Terminal A!). A lot of the reviews said they handed you the burger clearly marked as GF, but that was not my case (I ordered the cheeseburger, with avocado). I asked the guy who handed me my food to confirm the bun was GF and he said it was, so I went on blind trust. Before ordering I read that their fryer is not dedicated to fries, so I did not have fries. They also disclose on their site that the shake shack sauce does not contain gluten but it is made in a place that processes gluten, so to be safe I opted out of it and just asked for ketchup and mayo. Thankfully the blind trust paid off after thoroughly reading up through the reviews here to know what was off limits, and I did not get sick!
