Food and service are good--Pamela was an especially fine waitress, although I have had several others, who were decent. However, I recently discovered photos of Donald Trump and Lindsey Graham proudly displayed, so I do not plan to patronize this business any longer.

At the Roundabout Diner and Lounge, 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. 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 delicious cakes and pies right here at the Roundabout. From scratch! If you would like us to cater one of your events then look no further than Chill Catering, one of the largest catering companies on the seacoast.
