My daughter is GF/DF, so we got her a Pixar Pier Parfait at California Adventure. The man at the window had just handed the previous customer an ice cream cone, so I explained that this was an allergy order and asked if he could change his gloves. He took off his gloves, wiped down the cash register and the parfait dispenser, and then put on a fresh pair of gloves before making her parfait. I was so impressed with the precautions he took to make sure there was no cross contamination! He was being so careful, he almost forgot to ring up the transaction, LOL! My daughter was so thrilled to be able to enjoy an ice-cream-like treat all her own!
My child with Celiac had a gluten free lemon/blue raspberry frosty/soft serve cup and loved it!
