"In the basic presentation, the chili is poured over slightly overcooked spaghetti and topped with shredded Cheddar cheese; this is known as a "three-way." Adding onions or red beans makes it a four-way; adding onions and red beans turns it into a five-way. There is no such thing as a six-way, although oyster crackers are the customary garnish. Chili and cheese on a hot dog is called a Coney."
