I actually ate at the terminal c and terminal e locations, both without issue. They have different menus, too. I got the fish and chips at C and the house salad with salmon and jasmine rice at E. Food was good, and I had no symptoms afterward!
Staff was also kind and accomodating. Chefs at both locations brought the food to me and verified that i had an allergy note on my order before giving it to me.
The waiter at location C also mentioned that nothing with gluten gets fried, so they technically have a dedicated GF fryer.
