When I was a kid living on Franklin Ave, we used to walk a couple of blocks to the old DePasquale's Bakery and get great arancini there. This was eons ago, when DePasquale's was primarily a bread and Sicilian pizza by the slice bakery, way before Mozzicato's got involved and pastry became their forte. You might want to check out what is now Mozzicato - DePasquale's to see if they still carry them.
Yes, Maple Giant Grinder, but not sure if they make them every day, so please call to check before you venture out. :)
I've had 'em at Mozzicato's Caffe (next to the bakery) on Franklin Ave., too.
Let us know how you make out on your arancini quest!
