I have ordered twice from here without issue. Each time I ordered, the staff was careful to note "gluten allergy" on my order and change their gloves. Be sure to order the lettuce wrapped burger instead of a bun. The staff also repeats back your order in detail so you can catch if something is off. I also saw that the burgers and buns are cooked/heated on seperate areas of the grill. The only items cooked in the fryers are the fries, so it is a dedicated fryer by default. To be dairy-free, just order the plain patty without cheese. I am pleased with this location.
