At the Roundabout Diner, you can enjoy all your favorite diner classics. With a twist.

We serve breakfast all day, great burgers and sandwiches, Phantom Gourmet award winning BBQ, comfort food classics like meatloaf, roast turkey, and of course, local New England favorites like fish and chips, and the best lobster roll around.

(As seen on the Phantom Gourmet show on 10/17).

We also use locally sourced ingredients wherever possible, like bread baked just for us by When Pigs Fly Bakery, breakfast sausage made for us in Vermont, local cheeses, and more. And we make all our desserts right here at the Roundabout. From scratch!

And for a delicious, well-made cocktail, be sure to try the Roundabout Lounge, where you can also order anything from our diner menu.

The folks who brought you Muddy River Marketplace and CHILL Catering hope you’ll try our newest creation. The Roundabout Diner & Lounge.

We also have function room seating for up to 150 people.Great for weddings, rehearsal dinners, business meetings and more. Wi-fi, tv’s, projectors. Bus tours welcome.
