Located within St. Kate’s Hotel is this delightful pizzeria. Dough freshly made in front of you. Lots of healthy & delectable toppings. First time trying was delicious and I’ll be back. The CSMO 17 was delish!

Given this pizza was delivered 20miles via Uber it arrived warm and was still quite good. In store it must be excellent.
Neopolitan style pizza, maybe a bit too thin and floppy under carriage but nice flavor and crust had a nice soft chew.
Meatballs I thought were crazy salty. Almost inedible. Too bad, they’re flavor was pretty good if you get by the sting of all that salt.

I would love to give Proof Pizza 5 stars – because we loved the Carnivore pizza & Proof pizza – absolutely full of taste and a great mix of flavors. The reason for the 4 stars was the cheese pizza – it was underwhelming in the taste. As a pizza place, the basic cheese pizza should be good.
Loved the service, cute & clean place to pick up pizza. The second time we ordered the carnivore the pizza was a bit burnt, but we ordered the last 30 minutes of the night, so I’m guessing they were busy. We’ll definitely order from here again when we don’t have our teen with us (she’s a cheese only kind of girl, so it’s off the list for her:) meatballs were decent, and good choice of drinks. Definitely try the local Milwaukee beer!

We have tried the other food venues at the St. Kate and like them. This was the first time that we ate at Proof. Got nice welcome by the staff and an explanation of the food options, and the process. Ordered a couple of small pizzas. Waited for about 20 mins and the pager/buzzer went off.
Both pizzas were fresh, hot and flavorful. However, it was under cooked. Crust was good, the middle was not. Other reviews have complained about the pizza being soggy. It was horrible, but could have been better. I would try again and ask that it be done more.
Took the pizzas to the bar area and got to listen to an amazing jazz/pop ensemble. Overall, it was a good experience.

I love this eclectic pie shop in the St Kate hotel! Not only are the pizzas crafted to order the atmosphere is bright and refreshing. The crusts are delicately thin with a great chew to the edge. The toppings,and the ingredients of each of the sales etc are fresh fresh fresh! Pizzas can be taken out to the hotel lounge and bar area, eaten at a counter (reminiscent of NYC pizza places), or to go. I’m a repeat patron because I crave these pies!

Staff was polite and attentive. Pizza had a great flavor profile… however… it was a sloppy/soupy mess. Toppings & cheese would immediately fall off the floppy/wiggly slice. Even folding a slice down the middle didn’t help. Far too much oil. To be fair: staff seemed overwhelmed & backed up with orders during RNC

Unfortunately, these photos represent our last few experiences here so we won’t be back. First, the prices are out of control – $78 for three pizzas and two apps, takeout. But even that would be worth it for consistency and good quality, but Proof lacks both. All I could do is laugh when I opened the pepperoni pizza (as well as curse a bit). What is this, a pizza for ants?? The proof special was at least the size it’s supposed to be, but tasted only of giardiniara. It’s really a shame because Proof has the capability to be one of the best pizza places in Milwaukee but they seem constantly hampered by poor quality control. Will not be back.

Stayed at Saint Kate’s and was happy to find this pizza shop attached to the hotel lobby. Atmosphere is usually loud with live music in the lobby/bar/seating area. The prosciutto and mozzarella pizza was excellent! Good enough that we had it twice.

Really weird experience. No place to sit really. Pizzas take almost half an hour. No clue what their target market is because it’s not convenient if you wanna grab a quick bite of pizza and then go to the live shows over at the associate theater complex. It wasn’t bad, just really not worth a repeat.

Great tasting pizza, just a bit soggy for my liking. I prefer a crispier crust along the entire pizza, I ordered a margherita pizza and it was pretty watery. Pizza topping dripped right off and caused the crust underneath to be wet, if that makes sense. But overall, the presentation was amazing, SUPER quick service (the quickest pizzeria I’ve ever been to), and despite the pizza being a bit watery it still tasted great, Ill just have to ask for well baked next time!
