Very good and very friendly!

Huge breakfast will last you to dinner! Bacon was awesome. Although not a drinker, the make your own Bloody Mary bar was impressive idea.

or something like that. My husband and I had a discount ticket that Trish at Port Inn gave us. We had lunch there. This is a real diner with yelling and all. But the food was fast and hot and good. I guess they do a breakfast buffet here that is packed every Sunday. I can see why.

The Monte Cristo French toast was very delicious and the service was excellent. I would advise you to stay away from the homemade corned beef hash unless you want to taste and smell like garlic powder for the next 24 hours. It was not good!

First stop on a long road trip and the Roundabout set the bar high for our culinary adventure. We stayed at the Best Western and were planning on going into town supper but this restaurant was attached to the hotel and was well reviewed. We gave it a try and supper was so good we went back for breakfast. For... More

A local who used to enjoy Howard Johnson's when it was there but now the Roundabout Diner is priced right out of the realm. The tourists are too lazy to find other local breakfast spots which offer a much better value.

We visited twice on a recent vacation and were impressed both times. The staff are unbelievable - so pleasant and helpful. The food was terrific! You get a good amount of food for the price and the quality is great. You must try the Banana Cream Pie!

Have been here a few times at lunch or dinner. Good diner-ish menu. Food is fine. Service is generally OK but can sometimes be distracted. Good value.

We have visited the Roundabout 5 times based on expectations of good food. Except for a burger, we have been disappointed every time. We ate breakfast there this morning. First of all, the coffee was not hot. I ordered biscuits and gravy, hash browns and 2 eggs. The order came out wrong without gravy on the biscuits. The server brought... More

This diner was right next to our hotel. Our waitress was sweet, friendly, and ready with recommendations. Everything on the menu sounded so appetizing. The grand mariner French toast, corned beef hash, and bacon were delicious. Don't forget to add a personal pot of brewed tea. All of this for a reasonable price.
