I have lived in Stamford for almost three years now and still cannot find a great pizza place. There are two places that I do like very much, but they have their drawbacks: Colony and Spazzio.
I will admit that Colony's pizza is excellent. However, for one thing, it's a really unique pie with a crust that is so thin that it's crunchy. So, while it is excellent, it doesn't always satisfy my pizza cravings. Also, they don't deliver and they're even hard to order pickup from sometimes (they take the phone off the hook when busy).
Spazzio is a place I don't think many people are aware of (on Shippan). They make the more traditional neopolitan pie, but can be hit or miss.
So, please let me know who you think has the best pizza in Stamford. Thanks.
