Had an amazing time here with my family. I love all their gourmet style pizza recipes and all the unique flavors! It’s located right next to an ice rink so a great date stop. Great atmosphere to bring children. Their prices are very reasonable and they have great parking. 12/10 Would definitely come back here again soon.

Came in with a group of friends Owner was able to accommodate us by giving us two booths next to each other. The pizza here is amazing. I really like all of their gourmet style options and flavors for a very fair and reasonable price. They have a great atmosphere for watching sports and hanging out with your buddies. We got a couple pictures of beer, And a whole bunch of pizzas. Overall, I had an amazing experience here will definitely come back again!!!

This place is amazing and has great food!! Has great parking as well and located near an ice rink so perfect place to go on a date. Or you could bring your whole family they have something for everyone. The owner is very charismatic and you could tell he truly cares about the customer. I really really enjoyed all the various gourmet style pizzas and wings that they have highly recommend if you’re ever in the area.

This pizza was absolutely phenomenal! The ingredients are fresh, the dough is perfect, and it was cooked to perfection. I only stopped to grab a drink and had to take piece to go because it was so yummy looking! I like to eat pizza everywhere that I travel and this is going on my list of favorites! Stop by and say hi to Sid and grab a slice.
*** Update returned** grabbed a local beer and tried much more food. The BBQ Jerk wings unbelievable! Had the Nashville Wings, cheesesteak, fries, BBQ chicken pizza, and smores pizza for dessert. Everything is truly incredible. A must stop when I in the area.

I ordered this via Uber Eats so I cannot comment on the ambiance of this place.
I opted for the delivery option. For the first pie, I did half big bang (meat lover) and half quantum. For the second I got a cheese (hypothesis minus oregano). The pizza crust and consistency was good. It was a little burnt/charred so you could taste that a bit. My kids weren’t a fan of the crust so they didn’t eat much.
Another difficult thing about ordering their pizza are the names. It was a bit hard to order this online because it didn’t have descriptions.
I can’t say I would recommend them but that’s based off of one experience. I may try again at another time.

Located in a hidden spot but such a good find!! Slice theory is connected to an ice rink and serves up unique slices of pizza along with an extensive whiskey menu and salads and stuff too. Went after 9:30pm and got 4 slices for 6 dollars through flavorsavr!! The owner was super nice and very passionate and told us about the discount which is a company they partner with to reduce food waste. Pizza had a crispy crust and a lot of toppings. We had a great conversation with him, such a great local spot, def coming here again!

Hidden gem! So happy I discovered this place. You can tell they put a lot of care into everything and use high quality ingredients. The owner is the sweetest too.
And if you’re into whiskey, they have a very very generously priced whiskey selection.

Such a lovely place! The staff is incredibly kind and you can tell they really care about what they do. The pizza was absolutely delicious – amazing crust, high-quality ingredients, and a great variety of options for every taste. You can feel the heart and soul behind this business, it’s not just a restaurant – it’s something built with passion. I truly hope they succeed, they deserve all the support!

Highly recommend Slice Theory. The staff is very friendly and personable. Sid somehow remembers everyone when they walk in, and you instantly feel like you’re seeing an old friend. Our family has only tried a handful of foods, but the #1, in my opinion, is the Steak & Cheese (with the Wiz cheese, of course). Other family favs are the buffalo chicken tenders, chicken caesar wrap, and the breadsticks are delicious! Food never takes long, and quality is never compromised. Thanks for caring about your patrons and being passionate about your business, Sid and Rob!
