Don’t tell anyone we told you, but deep within the Cosmopolitan’s fabulous fine-dining floor hides a casual culinary treasure. Tucked between Blue Ribbon Sushi and Jose Andres’ Spanish tapas eatery, Jaleo, lurks an unmarked doorway, which leads to a long, narrow hallway. At the end of that corridor? An unnamed, stripped-down, order-at-the-counter joint, offering authentic New York-style pizza at reasonable prices. And it’s open until 4 a.m., seven nights a week.

We're pretty sure Mike the Pizza Guy made this on his computer.

The white, paper menu is stark and simple: slices ($3 for cheese, $4 with two toppings) and pies ($17 for cheese, $22 with three toppings), a couple deserts and drinks. Two beers are available on tap—PBR ($3.50) and Dogfish Head ($4.25)—and a $6 special gets you one slice of cheese and a beer.

The small space features a few counters and stools, a pair of TVs and a pinball machine. But cooler than anything else in the pizzeria with no name is the pizza, the fold-it-in-your-hand, thin-but-not-too-thin type you can find on most any street in Manhattan’s five boroughs. Seriously delicious.

Just keep it to yourself.
