On the Allergen charts they show what the "item" does not have. Yes, you still have to put into consideration CC with what you are eating. The item is prepared in the same kitchen that is preparing things with flour etc so when they are using the flour it goes in the air and lands on other items possibly. Plus you never know if the person who is preparing your food is not also touching items that you cannot have and then going back to preparing yours OR using a kitchen tool that was used on a gluten item.
Example: If you look at the Chilis website
http://chilis.com/ and put in your location under the Menu/Locations when the next screen comes up look near the bottom for Allergen info.....If you click on the wheat/gluten free one when it comes up read the top section where they warn you pretty much that they don't guarantee cross contamination (put in different words though). That is just an example.
It is hard not being able to eat at the places you use to love/go to, especially when it comes to friends and family wanting to go to those places.
GOOD LUCK!!
