I'm pretty sure pizza is the most perfect food in the world. It's comforting, can be healthy or not, and such a great dish to share or eat alone. 
It also can be topped with all kinds of things.  Veggies, Meats, and many other condiments.
Can be suited for any and every taste. My personal favorite is a thin, crispy crust. 
There are many different styles of pizza, including Detroit style.  Similar to Chicago style, yet it's rectangular.
