Did you know that you can set up group tours at Pizza Hut? I just attended one with our Mom's club. My daughter loved it! You would have to contact a Pizza Hut near you to see if they participate and how much they charge. Our tour was free. They just asked us to donate $1-2 per child for the server since she had to come in on her own time. Here is some information from Pizza Hut's website.
Call your local Pizza Hut store to set up a tour for your group! Ask to speak with the General Manager. Come in to see how pizza is made! Every child on the tour gets to make and eat their own pizzas! Available at participating locations.
