Wow. If you are ever near Portsmouth NH, this should be your first stop. My family has made this a must do anytime we are near. Everything we have ever ordered is always top notch. The breakfasts are unbeatable- pancakes, French toast, eggs, toast, bacon- you can’t go wrong with any of it. The atmosphere is fantastic, it’s like going back in time to a time when people took pride in everything that they serve. The 50’s vibe is present but not overwhelming, it makes you feel good and happy. If you are ever near the Roundabout Diner, you better stop, you won’t regret it!!!

I went from thinking that I could eat here every day to knowing that I will never stop here again. After calling 3 times to no avail to place a take-out order ( turns out the ringer is on low and can only be heard if someone is standing right next to it at the cash register), I went in person to place my order. The 2 hostesses could not have been nicer but it took 30 minutes to get my pancakes and hash browns when the restaurant was not terribly busy. It had taken so long that I just hurried to my car and headed out with my order, only to find that the pancakes were burned and hard as bricks while the hash browns were complete mush with some kind of mystery meat in them. Next time, I’ll skip the splurge and settle for a breakfast sandwich at Dunkin’.

Out of this world! AMAZING!!!!!!!! The turkey dinner was hands down the best I’ve ever had! The gravy and stuffing was so good it should be sin! But that amazing strawberry cream cake! Omg Super fresh strawberries throughout with real cream not that fake stuff! It was delicately & perfectly sweet! Please never change a thing! Restaurants like this are a dying thing nowadays and I hope you guys stay forever!

Great spot for a diner along route 95. Food is very well presented and great taste. Service staff are always friendly and welcoming. Most of the time there is a little wait but it goes fast.

Our go to breakfast and brunch spot. I could write about every single thing on the menu because there isn’t a bad thing I’ve had here. They also have very big affordable kids meals! The staff are amazing and so are the bloody marys. We absolutely love this place!

First time back in 3 or 4 years. Sunday afternoon stopped in and seated right away. Ordered the turkey dinner and a chef’s salad. Turkey dinner was a good sized portion of homemade turkey, stuffing, red bliss mashed potatoes and garlic green beans w/side of homemade cranberry sauce. Fresh, hot and very tasty. The wife’s chef salad was a huge plate of fresh greens, tomatoes, ham and turkey with a homemade ranch dressing. If you’re in the area and want a good meal of comfort food this is worth a stop. Oh and the desserts looked delicious but I was so “stuffed” I had to pass this time.

A typical diner experience. Our breakfast potatoes were absolutely horrible. Cold and hard, but the rest of the breakfast good traditional diner fare…

This place was really busy when I arrived but was worth the wait. This place had wonderful staff, great ambiance, and amazing food. The cinnamon French toast was the best I’ve ever had! I want to go back just for that! My wife had a Benedict that she enjoyed a lot as well. It’s definitely worth going to.
