We went during off hours and the staff was spectacular. Thy immediately suggested using lettuce in place of a bun and definitely knew what they were doing. The asked if it was an allergy, and when I said yes, they immediately changed their gloves. Nothing is fried other than French fries, so those are safe. We did not get the seasoning on the fries, so I don't know about that. The burgers were excellent and we would definitely go back.
