I am almost a regular

I love the Smoke House Salad with homemade Russian Dressing. I used to not go here because I generally don't eat 'diner' food ... but once I discovered the large and tasty Smoke House Salad, I am almost a regular.

We stopped here on our way to Hampton Beach because a friend told me that we had to try the fried pickles, which we did. We also had two of the lunch specials. The food was okay, the coffee was fair, service was friendly but slow considering they weren't that busy. Thought it was pricey too. Maybe we'll go back... More

The Roundabout Diner was a decent place to grab a breakfast or lunch. I didn't indulge in their dinner menu, but would assume that it on the same level as a Denny's type of place. They serve breakfast all day, which is a plus in my department since breakfast foods are some of my favorites. I had an omelette with... More

What a perfect diner! Easy to reach, plenty of parking, comfortable seating and really good food! Really good service too! The menu has something for everyone and the ambiance is great whether you just dropped in for lunch or you are stopping over from a long journey.

Located just off the Portsmouth traffic circle and attached to the Best Western, this restaurant is open from 5:30 AM to 10 PM. The decor is old diner and the music is 1950s rock. It is a bit more pricey than usual diner fare but the quality of the food merits the cost. We were staying at the motel and... More

We dined here on a Friday night in the lounge area although there was also plenty of seating in the main dining area as well. They have a really good selection of appetizers, soups, salads, entrees and daily specials. The chowder is thick and creamy and although the side salad was what you would expect, the portion was good sized... More

The Roundabout Diner was our favorite breakfast choice. We went on the first morning and couldn't wait to go back the following day. All the food was delicious! The prices are good and the portions will not leave you hungry.
