Came here one evening because my husband and I were craving deep dish. We ordered a split deep dish. I had spinach, mushrooms and tomatoes and thought it was great. I might not of ordered the tomato since this pizza has a lot of sauce which had large pieces of tomato in it already. The crust is a cornmeal which... More

The place was nice, waitress was great and we even got a warning to ask them to go light on the sauce from a staff member there. We should have listened. I thought I might be missing out on something if I did that, so I let them make it the way they normally do. It was light on cheese... More

From a suggestion by a co-worker, I gave this place a try. Since I travel often and in the St. Louis area on assignment, I am hitting the spots. As the St. Louis area is known for, provel cheese tends to replace mozzerella. Pi Pizzeria in the quieter part of the Delmar Loop did promote their "no provel" on the... More

We stumbled into Pi with hungry kids and not wanting to wait an hour at Fitz's on the loop. A little shabby on the inside, but great pizza.

We showed up at a slow point in the day and they had no trouble seating twenty of us together and we didn't have to wait very long at all for drinks or food. It's a pretty well kept and clean restaurant. The menu isn't enormous, but since it's Pizza, there are lots of options. I tried a pizza from... More

Did not have the pizza but by looking at others it did look the part. The wife had an awesome PI squared martini that was really good. Basil & vodka.....who knew. We shared an app of PI squared. They were little square kale and spinach bites that were prolly baked and reheated. NOT IMPRESSED that need to add more cheese... More

The decor was simple and uncluttered, the Staff was efficient but delightful, and the Pizza was over-the-top Delish... It was in a quaint part of St. Louis and we loved the cheery and busy ambience of the Pizzeria! <3 The BEST!

We went to the Lake Street Dive concert and went early to the Loop because we didn't know the area. We knew we could bring food into the venue. We just walked up to Pi and went in. It became apparent that this busy place would not work for the concert. Then we were directed to a room next door... More

We visited Pi last night and were not disappointed. We had reservations at a nearby Escape Room and were a little crunched for time. We were concerned that we wouldn't be able to get in and out on a busy Friday night without rushing. That wasn't a problem. We got right in and had plenty of time to spare. The... More
