Detroit style pizza is not just a thick pizza. Buddy's which was the original I believe is not really very thick. The idea is to put cheese slices around the edges to get a burnt cheese crust, and the toppings and cheese go on first, and the sauce last. It's not my favorite, but I do see a tendency around here to call any thick square pizza Detroit style and it isn't. Even Jets, which is a fine pie, is not really Detroit style.
