According to this list, the only businesses on Arthur Avenue that begin with a P are Pasquale's Rigoletto Restaurant, Paychex, and Peters Meat Market
If none of these places are the one that you were thinking of, then maybe the list is out of date.
It doesn't matter though, I was only thinking wishfully. It's going to be a long time before I can visit New York, I think (sigh)
and in the meantime I'm stuck in Seattle, which has exactly one (LOUSY) "italian bakery". It's staffed by neighborhood kids who don't know anything and care even less, and whenever I ask them if they have cannoli they are out.
What kind of Italian bakery is always out of cannoli??
((((sigh))))
Behold the glory that is Junior's!
