In and Out Burger
I just called In and Out's Corporate # and was told I would need to be called back on the tree nuts. They didn't know about peanut oil x-contam. with the cottonseed oil they use or the spices (which is just salt and pepper). Oh- I didn't check the sauce. But the shake mix they use is peanut-free though they have peanuts in the facility, the dairy told them they do everything to avoid x-contam. The buns are peanut-free. I will update when I find out more. Here's their all-night # available till 1 am or so PT: 800-786-1000
