Good food

We stopped here for breakfast on our last day of vacation. We were seated right away and greeted by our waitress. Our breakfast of eggs with potatoes and meat was delivered very quickly. Everything was cooked perfectly. There was much more to choose from than just eggs if that does not interest you.

The food is tasty and wholesome. I've enjoyed their burgers and egg dishes. My favorites are the chili and the pulled pork dishes. The coffee is really good also. They source local and keep it fresh and healthy.

Nice diner, with a 50's style decor. Good food, with reasonable prices. Highly recommend eating there. Sunday breakfast was excellent!

This place is just average. My burger was dry and bland. I wasn't thrilled with the sauce that came with the onion rings either. The shake was good though! All in all, it was wasn't bad, but it wasn't really good either. Just a diner...

Stopped in to this '50's themed diner on our way home to Maine. I had the best pot of tea (many to choose from, I chose Irish Breakfast). You get your own ceramic type pot with the tea strainer inside. I had hot tea throughout my dinner. You can purchase a pot if you really like them! We had a... More

Located between two hotes--Best Western and Holiday Inn--this diner is a convenient and good bet for good food, friendly service and reasonable prices for couples and families. 50s decor nothing fancy but spacious and clean. Angus burger was excellent as was turkey meatloaf (gravy on side)...great breads and homemade cakes and pies.

Service is always quick and staff is friendly. I've had breakfast, lunch, and dinner here multiple times and recommend Roundabout to everyone. It's nice to have an old fashioned diner not far from downtown. You can't walk out without having a piece of homemade pie or a classic sundae! This needs to be a stop when visiting Portsmouth!!

Food is good, and portions are generous. This is you local/typical family owned restaurant. A good choice for breakfast.
