With arguably the largest pizza slices in New York (they're bigger than your head!) at prices that are quite the opposite (they're budget friendly!), it's no wonder hoards of Columbia students have flocked to Koronet Pizza in Morningside Heights for years. The pies are the size of car tires and are served until 2am nightly, making this casual counter-serve the ideal place to stop on your way home from a night of imbibing. While there are toppings you can toss on for a little extra cash, we'd advise sticking with plain or pepperoni to 1) save money, and 2) enjoy the classic, greasy goodness as is. Once your reheated slice comes out of the oven, make like the rest of Koronet's customers and take a photo with it next to your face.
