Yesterday I went to Wagamama for lunch, checked out the menu and asked the staff for rice noodles instead of the wheat ones. She looked at the menu at my order, I said I am a Coeliac (I did not mention "GF" at all), she said there were several things I could not have so they would change them. The meal turned up, very tasty I cleared my plate and today no problems what so ever.
Having completed a survey its back to Chiquita for my free Fajita next week.
You can get good food, good service where ever you go and there will be occasions you cannot be catered for.
Do not be scared to talk to the staff!
