Do not trust their allergen menu! Our son has an egg allergy, and we were told that the brownie flavor did not contain eggs. We had the manager called to confirm this. It was not the case.
If you need convincing, look on their website. Go to their menu. Look at their Reese's Peanut Butter Cup flavor.
Their Reese's Peanut Butter Cup flavor does not list that it has nut as an allergen! Screenshots attached.
We went to the hospital after visiting this place.
