This just happened to be nearest to our hotel, so we took the easy option.A typical Diner layout, full of retro images from the 50s/60s Broad, good menu .Not the quickest service and, as usual, the air con was a tad cool, but the food was fine and ,naturally, served with a big smile !

Stopped by with a group of 14, no reservation, no problem. Waitress was fun and attentive and efficient - including separate checks. Food is better than "diner fare", large portions. Good value for the food. Interior designed to look like a 50's diner, including old rock n roll music. We're sorry we waited until the last night of our trip... More

We went here for dinner once and breakfast once and were quite pleased with both meals. Everyone in our party enjoyed their dinner and two declared the fries the best they had ever had. Service was quite good - there was a short delay when we arrived but our waitress had been sat a large party including 5 boys sitting... More

We were told the desserts were home cooked - and they absolutely were. I had the banana cream pie - splendid. My husband had the carrot cake - huge piece and so big we saved it to finish the next day.

We had a good dinner here, the lobster rolls were excellent! We also had a decent breakfast. The service was adequate but could have been more friendly. On a busy weekend I guess the staff were tired.

Frustrated by the terrible traffic and lack of parking downtown, we stopped at the Roundabout on the way to Maine. There were very few lunchtime customers but service was slow. My daughter pronounced her chicken sandwich the worst she had ever had, saying it tasted like it had been frozen and then microwaved. My salad was OK. the decor was... More

We were driving from Maine to Boston and stopped in for a late lunch. We were seated in the main dinning area with only one other table occupied. After sitting for over 5 minutes waiting to be served, with not so much as a hello, my son finally got up to speak to the hostess. After several more minutes our... More

Our great customer service is typically what stands out most to our guests and it is very disappointing to hear that it was not the case for you. I am looking into... More

We ate at the Roundabout Diner over the 4th of July weekend during a visit to Portsmouth to see the fireworks and we were very happy with the food, the service and atmosphere -worth the trip!
