If you tell them you have a gluten allergy, they wipe down the meat slicer, change their gloves, and make your sandwich on wrapping paper, use the squeeze mayo, special knife, etc. They also have the sub in a tub option if you don't want the Udis GF buns. And they have Udis GF Snickerdoodles! I like that I can watch them to make sure they are careful, which they always have been so far. Never gotten sick.
