<<Disclaimer: Verify this information before applying it to your situation.>> Hi! Culvers Restaurants are a chain in the Wisconsin-Illinois area. I'm really not sure where else they might be found. I just wanted to share with you that their vanilla custard (soft-serve) ice cream is GF. The manager was very helpful including showing me the ingredients list on the bag of mix that they use and then calling the manufacturer to verify the mono diglycerides. He called me back when I got home and told me that the vanilla custard that they serve is GF. He called me again today and said he had been thinking about it and wondered if since it is a dairy product, and cows eat grain, was that a factor? I explained that it was not and he mentioned again that he just wanted to make sure that it would be safe for my husband to eat. We really have run across some very nice people in restaurants who have gone out of their way to help. Barbara in Illinois
