Just want to let everyone know, my daughters and I just say down to eat at Olive Garden, ordered from the gluten free menu provided, and I chose to double check for the cheese (I've been burned by 'trusting' the restaurant biz too many times!).
I saw this thread about the cheese, so when the salad came out and the sever offered cheese, I asked her about it being dusted with flour. She politely reassured me that they do not dust it with flour themselves, but when I asked, said she could double check. Sure enough, it comes pre-packaged that way. They went and read the ingredients list on the box, and yes, it is indeed coated. DON'T EAT IT!
Thankful for this forum as a heads up- saved me days of pain and misery!
