If you head to Newport, there's Gary's Handy Lunch, Bishops Diner, or the Blue Plate Diner. I'm pretty sure they're open year round.
Down in Wakefield there's the Breakfast Nook II. I wonder where the rest are?
They have great eggs Benedict with asparagus.
I'd drive down there on weekends just to get out of Newport for a while
I very seldom go to Newport, I grew up on the Island, I do go to the Nook now and them, I like Phil's on Main St and our local LGS is just a few doors down.
