This location asks allergy or dietary when you order a lettuce wrap or bowl (without bun) for your burger. One person prepared my burger bowl start to finish without touching anything else. (They also changed their gloves before starting.) My husband was with me who eats gluten. They put his burger in a separate bag from mine. We also got a large fry to share and they put those in a separate bag too so his burger would not contaminate them. (Five Guys only fries fries, so there is no cross contamination in the fryer which is a nice treat!) I was very impressed with their food handling and my lunch was delicious!
