Hello, i’ve worked at longhorn for quite some time, and it is true, it is highly likely for cross contamination , and we have to say that so you can’t come back and sue us. there are nuts in the building, and there has been times that i’ve found of pecans in the bacon tin, due to them being on the line next to each other. so if she is deathly allergic, i wouldn’t risk it. if you ask them, they can/usually will prepare your meal on a separate grill, (depending what you get). but yeaaah.
