I ordered the blue cheese potato chip appetizer. It was excellent and enough for a meal! So I didn't even order an entree, but I did get a triple chocolate frappe, which was equally excellent. Server Tiana was attentive and very pleasant. It seemed a little pricey for a place that calls itself a diner, but it was still worth... More

Great food and service. Pancakes are large fluffy and moist. Coffee hot and not bitter. Has a great 50's theme going on inside. Never had lunch or dinner, but will try. Easy access off I95

Some of the best breakfasts in the state are served all day long at the Roundabout. The fifties decor is not original but fun all the same. The standout is the food and the quality for a very fair price. If you don't know what you want, just close your eyes and stick your finger one the menu. No matter... More

Just finished eating dinner here. Between the eclectic diner atmosphere, sweet waitress and large plates, the experience was worth coming back. It may be a little more than average, but the portions are large and the food is quality. My husband is an avid lobster roll eater and he said the Lobster club sandwich was better than any roll. I...

Recently stopped in for lunch it was ok but not great. The prices were high and my husband had the Ruben sandwich which was not at all worth the price he was charged.

I brought my 92 year-old Dad in for lunch in a wheel chair. We were greeted by Pamela, and given thee most excellent service! She was always there to help without being at all intrusive. She cater to my Dad's needs with patience and efficiency. We really enjoyed our visit. It was a great success! Thank you Pamela!

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!

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.
