NOTE: The chocolate wafers can be typically be found on the baking isle, or the cookie isle (depending on the grocer). Nabisco and Keebler make boxes of chocolate wafers for crusts. You can also use another chocolate cookie if you prefer. You'll just put them in the food processor or blender to crush them into crumbs. If you do not like chocolate crust, you can use Graham crackers instead. I'd use 2 sleeves of the graham crackers, that's about 20 - 22 crackers, and crush them into crumbs, add the butter, and press into pan just as you would the chocolate crust. But seriously the chocolate crust tastes best with this cheesecake in our opinion!
