The Cauldron Cafe is not exactly a place where you or I might eat but all the customers seem to really love the food. Your job is to serve a certain number of customers per day and you do have to be past as there is a time limit. The customer will ask you for a sandwich and you'll have to do your best to match the picture with the ingredients. Build from the bottom up and when you're done, click on the sandwich and drag it to the customer and you'll be on to the next sandwich. You have to be quick and you have to pay close attention to the ingredients in order to make your daily goals but there's no harm trying in Cauldron Cafe even if the food is pretty disgusting.
