Could not find a restaurant with gluten-free food at MIA, but according to an online review, someone else had gotten a gluten free meal at Islander. So we tried the gate D48 location, even though the hostess said they did not offer gluten-free food. The server, though, was very helpful and arranged for a gluten free meal of delicious fish and vegetables! I would give it five stars if the restaurant simply trained all its staff (including the hostess) about gluten and indicated which items on the menu could be prepared gluten-free. There is an unfilled niche market for gluten-free meals at MIA; it would not take much for this restaurant to fill that niche well.
