Atticus has had a cafe and bookstore on Chapel Street in New Haven for decades, adjoining the Yale British Art Museum. They recently took over the old site of Romeo & Joe’s on Orange Street and turned it into Atticus Market, which has prepared foods, select groceries and gifts, and some picnic tables out front. That’s where they sell the pizza, and I believe they only do it Thursdays through Saturdays, until they run out (around 50 pies a night).
I’ve been there for breakfast and lunch but haven’t been able to make the pizza timing work yet despite good intentions.
You might also consider trying Zeneli, Bufalina, One6Three or better yet grab takeout from Olde World and bring it to 12%.
