★★★★★ 5.0 Amber Wooff · Feb 2026

First timer tonight and WOW! I took home the classics, cheese and pepperoni. Sometimes sticking with the basics tells you everything you need to know about a pizza place (and boy did it!). The pepperoni was large, fresh, and thinly sliced, full of flavor without being too greasy or overpowering. The crust is true New York style. It’s thin and foldable with just the right amount of crunch. You get those beautiful air bubbles in the dough and that light crisp on the bottom that gives it texture without being too hard. The sauce really stood out to me. It has that simple, fresh tomato flavor, not overly sweet, not heavy, just balanced and clean. I could taste the quality in the ingredients. The cheese ratio is spot on too. It’s melty and so flavorful. Everything tasted fresh and thoughtfully

It’s hard to get 5 stars across the board, but they did it. This place is so cool and eclectic inside and the staff was really friendly. I appreciated their recommendations and honestly about the wait time (which was only a few minutes). The pizza was fresh, wood fire cooked, crunchy crust with great sauce. I got regular pepperoni and my fiancé got their Italian sausage with ricotta and peaches. Both were fantastic and huge slices, for only $5 each. We order the Nashville hot fries and ranch and they were made fresh with a good amount of seasoning on each fry. Savory with a hint of sweet. Definitely my new pizza place!!!!

Great pizza and fries! We tried 1919 and four and loved each. The 1919 pepperoni was a classic and the combination of brussel sprouts, bacon, and mushrooms on four was a really tasty twist! We also tried truffle and salt and vinegar fries with ranch—BEST RANCH IVE EVER HAD. Amazing quality. I will be back. Really inspiring to see one person running a place so well!

Give this groovy pie shop a try! We enjoyed a cheese slice & truffle fries. Pizza crust was crispy, and the homemade aioli for dipping is a must. Small space with no indoor seating, all orders are to-go.

Honestly some of the best pizza I have ever had. Definitely worth stopping by. Must get Nashville fries, great job. Hot honey amazing, not really spicy, but outstanding flavors. Maybe in the future a spicy or bbq pizza would change the game, and also an extra protien option. Very well done. Just my personal opinion. Very well done, much respect to the owner and DEFINITELY worth your time and money. Continue being innovative, he is on to something
