Re:The Worst Pizza I've ever eaten
The tri-state area (New Jersey, New York, CT) is the place to get the best pizza. I have had good pies in California.
We were on a work trip in Huntsville Alabama a couple of years ago and they recommended Pizza Hut when we asked about a good pizza place. Florida had a couple of decent places and Nebraska had a couple decent ones.
Never been to Chicago and had the style, but really, the best pizza in the US you will find in the tri-state area. I lived in NJ, I go to New York often and live in CT.
