have eaten at The Roundabout for a long time now. The menu is wide and varied, great 'diner' food. Highly recommended for a casual atmosphere and a good meal. Conveniently located around the Portsmouth Circle.

The food is a treat. We especially enjoy the bread ( When Pigs Fly ) and the delicious Irish Breakfast tea. When you go in, be sure to check out the dessert case, just in case you need to plan to have room!

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.
