My DD has severe nut allergies and we always go to Beaches and Cream. We have ordered the kitchen sink but it required a lot of substitutions. They brought us out an ingredient list for all the products used in the sink. They are excellent about opening a new container of ice cream and using a clean scoop. We have been going there for about 9 years and have never had a problem. But it all depends on your comfort level. My DD has to actually consume the nut in order to have an anaphylactic reaction (although just the smell makes her nauseated.) While she has had many reactions due to cross contamination, thankfully none of them have happened at Disney.
