I’m a Phoenix area guy and a "Dogger" There are any number of "Chicago Style’ dog shops out here. One in Scottsdale in the strip center at Shea & Scottsdale Rd. The Chicago Hamburger Mentioned before is good. They have good Fries and "Sliders" too. Daves Dog hause on University just east of Mill Av in Tempe Serves Dogs made in New England, Boston style Buns. Teds at McKlintock and Broadway in Tempe serves a dog made in Buffalo NY that’s chargrilled.
