I love this taste-test done by two Chicago expats living in San Francisco. David Ayman Shamma and Daniel Raffel put together a panel and had "a scientist and cognitive psychologist specializing in human-computer interaction" design the sampling and rating protocols:
On December 12th, we gathered our 12 testers in total. Entrepreneurs, product managers, engineers, scientists, designers, a pizzaiolo, a librarian and a lawyer rounded out our collection of people from around the bay area; half of these testers identified themselves as those who prefer New York pizza over Chicago. Three cheese Chicago-style pizzas were brought in locally from: Little Star, Patxi's, and Zachary's. The 2 shipped frozen and reheated from Chicago were Lou's and Gino's. All these pizzas were of Chicago Deep Dish style--not the "stuffed" variety. Dr. Churchill, who was not taking the test herself, designed a ' pizza score card ' to measure peoples judgement on each pizza on a 1-5 scale: Appearance, Smell, Texture, Taste, Finish, and Overall-loving-feeling. Each pizza was presented unbranded on a standard pizza board labeled only with a number. Each taster drew numbers from a hat to determine the order in which they tasted pizzas. This helps to control the error of the pizzas getting cold as they sat out.
Long story short, SF-based Patxi's came out on top, but do click through for the whole shebang.
