Great diner experience. I've only had breakfast fare there, but it is consistently awesome, large portions, well-made and served by pretty attentive, efficient and hustling servers. I had a corned beef hash eggs Benedict most recently; Wow. Every heart-clogging bite was pure pleasure. And the Hollandaise was actually really good (I'm a bit of a snob here). The excellent home...

They are very proud of their food and service. In both visits for breakfast and once for dinner, I have been less than impressed. They seem to have a loyal local base, but I probably won't be returning during my stay (6months)

Regular diner. Ordered pancakes. Came to table undercooked. Server was apologetic and new ones quickly came out. They were yummy. Decent experience. Very nice bathroom.

The Roundabout is good for a basic almost home-cooked meal. Lots of options to choose from. Hours are convenient and there is plenty of parking.

This is a fun place for breakfast. You feel you've gone back in time, and there are so many options for food. Some creative things too, like Challah french toast, which is amazing. Reasonable prices.

Good diner for breakfast. Menu options are adequate service was slow to start but once our waitress "found" us it was fine. A little pricy for diner food but all in all fair for what you get. I do recommend.

We ate here multiple times during our scrapbook convention at the Best Western Hotel in March 2017. This place is BUSY. The diner is kind of nostalgic & just that, a diner. The food was surprisingly a little higher than I would think for a diner but was good. A very good menu with many choices. I had the haddock... 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.
