Turtles at Big City Pizza.
Big City Pizza is a pizzeria in New York City in the Teenage Mutant Ninja Turtles Adventures comics issue Of Turtles and Stones and Mary Bones, where the Turtles are seen ordering pizza in the beginning of the story.
The pizzeria employee, smoking a cigarette and dropping ash, never says a word as the Turtles place their order. Leonardo requests their largest whole wheat pizza with onions, mushrooms, peppers, black olives and cheese. Donatello adds that they want extra cheese, lean ground beef, and a smattering of sweet Italian sausage. Michelangelo picks up the order from there, requesting lots of pepperoni, lots of rhubarb and kiwi fruit, fried clams and peanut butter cups. The only thing Raphael asks is that they hold the onions on one quarter of the pizza.
The venue also sells Turtle soup.
