This Sunday afternoon we taking my 90 year old mother to visit a family friend in Riverdale who is recovering from a recent sadness. If we're up to it (and get there early enough to avoid a wait, say 3 PM) we might try to go to Roberto's in the Arthur Ave neighborhood. But most likely, we will opt for something easier. And here I am at a loss. Does anyone have a suggestion in Riverdale, Kingsbridge, southern Yonkers, etc. for the four of us for a Sunday afternoon dinner.
