Not much to look at from the outside, but the inside is a cute 1950's diner! Great décor and music, and the food is even better. We had breakfast (served all day), it was freshly made and tasty, generous portions. Would definitely visit again!!

This place is NUTS! It is huge, yet you feel you are in an old diner somehow. The staff really works very hard. How they keep from crashing into one another is a mystery. Extensive menu with something for everyone. And listen up all you other "breakfast" joints in New England, not only do they offer real maple syrup, it... More

Excellent choices friendly staff. Try the pulled pork grilled cheese on sourdough or the BLTCA....the Monte Christo was also a hit with our group.

We didn't wait too long to be seated for breakfast. The menu was extensive and we enjoyed the country gravy Benedict and a regular breakfast plate. The toast was thick cut, the eggs perfectly cooked and the special maple sausage was yummy. I'd go again without hesitation.

Waited 20 minutes, then my food didn't arrive with my family and it took another 10 minutes+. This happens, but the indifference was irritating. The food was tasty, but they serve textured fries, same as at Burger King. Plus, with the exchange rate, for three people, lunch was $65. Pricey and left disappointed.

As a result of Phantom Gourmet's rave hype, we ventured to Portsmouth. The "Phantom" gave them a ~~"Suburu-worth-driving-to-award" for their banana cream pie as well as commended them on other dishes. We are not quite sure what the hype is all about. Pros: Host / reception was nice, pleasant Service / waitress was attentive, polite, efficient Buffet Host was accommodating,... More

We have been here several times and the meals have been uniformly excellent. My favorites are the lobster BLT and the eggs benedict. Also, this was our first time here on a Sunday morning and they had an extensive buffet, with separate seating, for twelve bucks for all you can eat. This is a great value!

We stopped in for breakfast. The diner is super clean and the staff is very accommodating. The portions are large, our coffee cups were always full. My husband loved his eggs with thick bacon and the thick marble rye toast. I ordered their oatmeal. It arrived in a soup bowl! I thoroughly enjoyed my breakfast as it was steel cut... More

The Roundabout is a little bit of everything- diner, restaurant, bar, function hall, take out, etc,.... They serve breakfast all day which I always love, but we stuck to the dinner menu this time. The menu is extensive with all the diner classics. Service and food were good. Desserts looked great, but we resisted. Give it a try for comfort... More

Description
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.
