Solid New York-style slices near Union Square with standout service and convenient hours, but prices and portion sizes feel steep for many.

Why it gets a B for overall quality

Union Square Pizza & Kitchen delivers reliable neighborhood pizza with strong food quality anchored by crisp-chewy crust and balanced sauce when pies arrive fresh. Attentive, friendly service and convenient Union Square location make it a practical choice for hotel guests and quick meals, though inconsistent execution between fresh pies and reheated slices and pricing concerns prevent a higher grade. Solid execution within its casual counter-service category, but lacks distinction to compete with premier local pizzerias.

Restaurant Summary

Steps from the Hilton, this counter-service pizzeria feels unassuming and handy for conference goers and hotel guests. Reviews highlight warm staff who offer tips to save money and time, with notes like, "They suggested a better combo and had it ready fast." The space is small and simple, but the convenience near Union Square and quick slices make it an easy move when you need fuel without fuss. The cooking leans classic New York slice shop with a few twists: hot honey on the New Englander, a pesto-forward margherita, and a sweet-leaning BBQ pie. When pies come out fresh, the crisp-chewy crust and balanced sauce win repeat praise; reheated slices can vary. Prices run high for the portion size, which several diners accept as the Union Square premium while others flag as a deal-breaker. Families manage well here thanks to plain cheese and pepperoni, simple pastas, and shareable salads. Slices are easy for kids, though portion sizes can feel small for the price. There is no noted kids menu, but familiar options make it workable; the best bet is a fresh whole cheese or pepperoni instead of held slices.
