The aesthetic at Scarr’s is ‘70s diner meets your California grandma’s home meets a modest houseboat; details like orange-lacquered serving trays, a millennium-era stock photo of the Manhattan skyline, and a framed Mets flag are edged with self-aware born-and-bred–New Yorker appeal. The owner cut his teeth at Joe’s, Artichoke, and Lombardi’s; here, he can be found behind the counter, manning the gas oven in his signature flour-flecked black tee. Snatch an unctuous white slice or order a personal pizza — healthily sized to satisfy two to three people — and stake out a backroom booth or stool at the wraparound bar. The old-school menu board lists just five slices (original, Sicilian, white, pepperoni, vegan), but there are plenty of toppings: Go for a heaping red-onion-and-pancetta Sicilian pie, which is wonderfully thick. Tomatoes are locally sourced and flour is milled in-house, so conscientious pizzaphiles can rest assured that no canned products were used in the making of their late-night slice.
