Knowledgeable staff at the Terminal B location. Items they can make GF are marked on the menu. I ordered huevos rancheros to go for breakfast, specifying GF. Waiter who brought my order out told me she subbed fruit for the fried potatoes b/c they put panko bread crumbs on the potatoes. She told me she made the sub in case I had celiac. I appreciated her attentive service.
