many times for many years I would sail from Newport to Dutch Harbor and anchor there for the night. My girlfriend and I would row into that little marina there and then walk up and over to The Narragansett Cafe. In those days it was mostly locals but a friendly place with reasonable prices and good food. I'm sure it hasn't changed. I have a lot to do between now and Jan 1 but i'll try to make it Sunday.
There are new owners for the last couple of years,John and Cathy, and they are very nice people.The place still has that "old new england" feel to it. I hope you can make it.
