GQ recently came out with a list of the 25 Best Pizzas in America. My personal all-time favorite, Buddy's Pizza in Detroit, was #15. There were several Detroit pizzas on the list-- I have always been of the (biased) opinion that Detroit is one of the best pizza cities in the nation. The reviewer, Alan Richman, ranked New York as the top pizza city; San Francisco was second, followed by Detroit at number 3 and Chicago was fourth.
However, Richman only visited ten cities. Sadly, no DC pizzas were featured.
