Pizza out here on the West Coast sucks. My apologies to my fellow Californians, but if you've ever had pizza in New York or Chicago you'd agree with me. Fortunately we've got this place close to where I work that has NY style pizza in a place that is actually run by Italians. They make a pretty good pie but still not as good as what you'd get out East.
For NY style I like plain cheese, no need for anything else. For Chicago style though, lots of meat is the way to go.
