Here's one person's list of the top 25 pizzerias in Chicago. Turns out a New Haven style place is ranked #2.
2. PIECE
(NEW HAVEN) When Billy Jacobs opened Piece in 2001, he was told New Haven– style pizza would go over like a lead pepperoni in Deep-Dish Land. Wrong. Piece’s astonishing plain pie (sauce, garlic, Parmesan, and oil on a chewy-crisp, hand-formed crust) replicates New Haven’s legendary Sally’s Apizza without the coal oven (Piece uses a Middleby gas oven). For Jacobs, a Connecticut native whose great-uncle’s produce market was intertwined with Sally’s in the 1940s, the sun still rises and sets in New Haven. “I can confidently say that the third-, fourth-, or even fifth-best pie in New Haven would be the best pie almost anywhere else,” he boasts. And you thought New Yorkers were pizza snobs.
