Allergens in Shakes and Desserts
Most shakes and floats contain milk and egg. Several items also contain wheat and soy, including the OREO Cookies and Cream shake, the S’mores shake and the Biscoff shake. The Reese’s Peanut Butter Cup shake contains peanut, so it is not suitable for anyone with a peanut allergy. The nutrition information also notes that cross-contact with tree nuts may be possible in all shakes because of limited-time offerings. If you have a serious food allergy, speak with the staff before you order.
