Service was OK. Food was on par with most diners. Breakfast served all day. In all fairness, we did not try any of their famous desserts, but don't expect they differed from thise of most diners. I LOVE diners, and this is in keeping with most -- but nothing special

I've been here twice. The first time was amazing. Incredible pancakes that are out of this world. Friendly and attentive staff. The second time I sat waiting to be seated 10 minutes after they opened with no one in the place for 10 minutes. The young waitress in the kitchen looked over at me and just kept working. She was...

We enjoy both breakfast and dinner here. Food was good, service was great, and parking was plentiful. Prices range from $$ to $$$ . They serve very large toast, and the teapot is a nice touch. They have a small bar in the back. Check it out!

Got the turkey pot pie and greek burger. Portions are large and the burger came with a fried pickle! The pot pie crust was more like a thick cracker. The staff us friendly although, as noted by another reviewer, the aggressive political posters probably mean that not all are welcomed. That was off putting. The decor is pretty cool otherwise.

This diner is located on the traffic circle in Portsmouth. I have eaten here a couple times but only at breakfast. There breakfasts are good and the portions are good sized. I had a huevos rancheros with home fries and tortillas. It was very good. My wife just had a bagel. The other couple with us had regular egg and... More

This restaurant is modeled on a 50s diner, with 50 and 60s music, home made milkshakes and large hamburgers. The service was good, so was the food and it felt very comfortable to be there. Because they are associated with the hotel next door you can get a coupon for a free breakfast when you overnight. The desert case is... More

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.

We spent last week in the hotel hooked to this restaurant with limited time for meals, we ate all of them here. The wait staff was great. The first two days the food was fantastic. So much so that I was so looking forward to having breakfast there again on Sunday. I just loved their eggs and the toast was... More

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.
