A tiny Union Square slice spot with genuinely creative Roman-style pies, strong vegan and burrata-heavy options, and a love-it-or-leave-it price tag; go for the pizza, not the seating.
Unregular Pizza delivers exceptional food quality with inventive Roman-style slices and standout specialty builds that justify its reputation as a Union Square destination for distinctive pizza. Strong service execution and quick turnaround make it ideal for a fast, flavorful bite. However, moderate consistency issues with occasional soggy or cold slices, combined with minimal seating that limits it to takeout-focused visits, prevent the grade A territory that would require more reliable all-around excellence.
Unregular Pizza is a tiny, high-energy Union Square slice stop that people either rave about or nitpick hard, which is probably exactly what happens when a place gets serious about being different. Reviewers keep coming back to the same picture: crunchy square crust, burrata-heavy specialty slices, and a shop that is much better for a quick stop than a long hang. One diner summed up the mood nicely: the pizza may be small-format, but the flavor can hit big when the slice is fresh. The cooking leans inventive but still very much pizza-first. Expect Roman-style squares, rich cheese-forward builds, some playful Italian-American twists, and a few menu items designed for adventurous eaters rather than purists. The strongest feedback centers on the Cacio e Pepe, grandma-style slices, burrata-and-pepperoni combinations, and the vegan options; the biggest complaints are about overpriced basic slices, occasional sogginess, and the rare underwhelming or cold piece. In other words: worth it if you want a fun, distinctive slice, not if you are chasing classic no-frills dollar-slice energy. Families can eat here, but only if they are comfortable treating it like a quick stop. The menu has kid-friendly basics such as plain cheese, pepperoni, grandma slices, chicken sandwiches, and even a Nutella pizza for dessert, but there is almost no real seating. So yes, the food itself works for kids, especially if they like pizza, but the space does not. If you need a relaxed family sit-down, this is not that kind of place; if you need takeout before the park or hotel, it fits much better.
