Edit: personally too worried about cross contamination to eat at Jimmy Johns anymore Fantastic. The unwhich is a lettuce wrap of whatever you want. I love the Hunter's, which is roast beef and cheese. They are well trained for allergies at this location. They put on new gloves. They put down fresh paper and make the unwhich on the paper. They give mayonnaise packets instead of using the shared spatula. There is always the possibility of cross contamination, but I have never gotten sick here unlike other sandwich places. Beware the tuna salad, it has Gluten but not from the mayonnaise, lol. Jimmy John's has become our go to for bringing home a quick meal.
