Once seated we asked what GF options they had. They politely directed us to a different restaurant in the air port that had GF options.
Even though this restaurant does not have a gluten free menu and items are not marked, they showed me the ingredients for each item in my dish and were willing to sub lettuce for bread/chips. The wait staff was very friendly and knew the ingredients in addition to showing them to me to confirm. They were very willing to work with me.
