I was in town for a conference and apparently St. Louis was not ready for a crowd. The service was slow as the conference had over 10,000 attendees. The pizza is great, crust is delicious. They have a vegan/gluten free menu. Staff is knowledgable.

Superb toppings and I absolutely loved the crust! We were watching a show at the Pageant and a group next to us brought in a thin crust pizza from Pi.

We had one deep dish and one thin crust and both the adults and kids in our party loved both. Our server was pleasant and... More

Went here during a convention at the Edward Jones Dome. The service was excellent and the food just as excellent. If you are there on a weekend, you might want to go during off hours (2-4) for lunch. It was packed when we tried to go there during typical lunch time, due to the event at the dome.
