Good article. Now I'm hungry. Nice to see 4 Detroit-area Pizzerias made it on the list. People think Detroit-style pizza is square with toppings under cheese, under the sauce. While that's in keeping with Buddy's, Nikki's, and Shield's style, it's not the norm in the area. There are so many styles of 'Za around here. Friends that travel here on tour, or pay a visit from out of town, always remark on how good the pizza is around here. Sure Detroit spawned crap chain pizza like Domino's and Little Caesar's, but there's probably more pizza per capita then even New York (factoring population, not sq. miles).
Here's my list of Detroit Pizza to enjoy, if for some reason you come to this god forsaken city.
Supino Pizzeria - Eastern Market in Detroit
Kruse & Muer - Rochester, MI
Jet's Pizza - various locations
Buddy's - various locations
Shield's - Troy, MI
