I have eaten at Waldo Pizza in Lee's Summit many times over several years and have never had a reaction. I know many celiacs in the KC area and we all consider this one of the safest places to eat in KC. Not only that, but they have the best gluten-free pizza in KC. I always order the combo, but if you select certain toppings, I suggest you ask the manager which are gluten-free. They have a list they refer to.
