went there for breakfast after seeing it on NH chronicle and was disappointed had 2 lousy omelets and coffee and it came to 28$ without tip to much to pay for 4 eggs and a little filling drive by and eat somewhere else

Being attached to a hotel and having "Diner" in the name gives the wrong impression in my opinion. Roundabout serves a great breakfast AND lunch. I have never had a bad meal here and most have been very good. The have lots of seating but on weekends there is usually a considerable wait during "brunch hours". Service can be hit... More

Portsmouth has been blessed (honestly, that’s how our kids feel about it) with the opening of the Roundabout Diner (on the Portsmouth Traffic Circle at the edge of the City ... chances are you’ll drive right by it on the way in or out of town). The kids just love the comfort-food (gourmet-quality comfort food to be sure), and mom... More

We LOVE the Roundabout! I'm always amazed when people say they've never been. Went in for Sunday dinner and beat the rush! Never had a bad meal, and I've always left full. Service and prices are great, and it's such a fun place. I got the Alamo burger and mum got the pulled pork tacos, both were excellent, as usual.... More

We stopped in the roundabout diner today for breakfast. It was filling and delicious. They serve When Pigs Fly toast which is a great compliment to any meal. The Bloody Mary bar was phenomenal.

Not only is their breakfast excellent but the staff is super friendly and smile! Every time we are in the area we stop for a great meal. The Best Western omelet is delicious and prices are reasonable. See you again!

I ordered the blue cheese potato chip appetizer. It was excellent and enough for a meal! So I didn't even order an entree, but I did get a triple chocolate frappe, which was equally excellent. Server Tiana was attentive and very pleasant. It seemed a little pricey for a place that calls itself a diner, but it was still worth... More

Great food and service. Pancakes are large fluffy and moist. Coffee hot and not bitter. Has a great 50's theme going on inside. Never had lunch or dinner, but will try. Easy access off I95

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.
