One of the city’s most famous pizza places, Pi is the joint where President Obama himself stopped during a campaign visit to St. Louis. The pizza here is different from your typical Pizza Hut fare. Pies are extremely deep dish and made with an unusual cornmeal crust and a very chunky tomato sauce. The sauce goes on top of the toppings and cheese! Dozens of interesting toppings listed on the menu, from Amish chicken to fresh rosemary to gorgonzola cheese, are sure to add some pizzazz to your pie. Gluten-free crust is available.
