GF subs on Udis rolls. They wash hands, change gloves, clean the grill and prep the GF sandwiches in a separate are. They are very careful to avoid cross contamination so it may take a little longer to get your food than normal, especially if there is also a gluten sandwich in your order but we don't mind. We want them to take all the time they need to make it safe to eat. We have eaten here three times in the last couple of weeks and my daughter has not gotten sick.
