Buddy's and Supino's are both good. Niki's isn't as good as it used to be, but it's still pretty good. Pizza Papolis is always good. Of the more franchisee establishments, of which Buddy's and Pizza Papolis could be considered, I definitely have to agree with Cottage Inn and I Amicci's is pretty good.

Of course, Buddy's and Niki's get the nod for carrying on the Detroit style pizza concept. It takes a lot more than being in the Metro area or within the city limits to truly be a Detroit style pizza.
