★★★★★ 5.0 Luda Krit · Feb 2026

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.

★★★★★ 5.0 Lacie Melville · Jun 2025

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.

★★★☆☆ 3.0 Kevin L · Dec 2025

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.
