Driving Boston to Narragansett, RI
I agree with a few of the places Sean listed. Crazy Burger is great variety and decent prices with byob. Turtle Soup is very good, can be a very long wait for a table, but usually worth it. The "short board" is the better menu with appetizer portions and excellent prices. I have gone in with a friend had a couple of appetizers and 2 glasses of house wine each and spent around $50 for 2 people. (Caution-do not order the duck). Trio is only about a year old and is still working out the bugs. Nice atmosphere, but very pricey for very small portions. Small portions are fine for most people, but you will spend a lot if you have hungry children. Service is also very slow and there is no good reason for it. Jim's Dock in Jerusleum has very good food, good prices, and byob. Spains' in Narragansett is also very good. Good prices with very good portions, excellent food. Pelly's for breakfast on the north end of Narragansett is very good, and inexpensive, and at night it becomes Wiley's (they share the space) also excellent food., byob.
My Favs are The Starboard Galley on Matunuck Beach road in Charlestown:
Estia Pizza & Restaurant
To name a few
