This is Our Lady of Grace Church on Avenue W in Gravesend, Brooklyn. It's where my parents were married and I was baptized. I haven't been there since I was age 11. It's waaaay smaller than I remember it, but Google Street has shown me that's pretty much the case with everything from my childhood.
Checking out the parish photo collection, I see that it's still very much an Italian congregation. This widowed-support-group Christmas party gave me a laugh because it is so familiarly Italian. As you get deeper into the images you can see how they made the waitstaff staff abandon their posts and join the party. There is no way a group of older Italian women would allow them any say in the matter. If they say party, you party; they won't let up until you submit.
If my grandmother had been there, she would have tried to help them clear the tables and do the dishes.
