There’s LOTS of great apizza in the greater New Haven area. Sally’s is my #1, Modern #2. I miss the Spot on Wooster (the new version is not the same thing). Angelo’s in North Haven (RIP) and Tolli’s (RIP, Tolli himself gunned down in armed hold up)(East Haven) are badly missed. I never heard of Zuppardi’s, but I wouldn’t be surprised if it is excellent.
Pepe’s will do, and it has seniority, but far from the best in my book.
Everyone around New Haven knows about Zuppardis. It’s delicious. But West Haven is a side trip most New Haven visitors might otherwise avoid.
I’m a Detroit-style loyalist, but New Haven definitely has the best (a)pizza in the US.
