We have used them in the past for cones from the place right across from Tuskers (soft serve cones)....most recently we did this August....I would just ask at the window and see....I think I read on these boards that it was only good at one of the carts....don't know if that was someone who actually tried it at the soft serve place and was refused, or if they just read it somewhere....we have gotten the soft serve several times with the meal voucher coupons.
