Located just outside Mystic, CT, Octagon prides itself on offering the finest steaks and freshest seafood everyday. Our menu changes seasonally and celebrates local ingredients harvested right here in our beautiful state of Connecticut. To our pleasure, our guests are travelers from around the globe and neighborhood locals. From our open grill and wine cellar to our one of a kind artwork and glass sculptures, we truly believe dining should be an experience, not just a meal.

Good food but pricey

We had lunch here before, but we were in for dinner this time. Food and service was very good. We felt it was a bit overpriced. We would go back but just be more conscious when ordering.

As residents of New London for 30 years we consider the Octagon as the best overall quality restaurant in Southeast Connecticut. It has a warm, cozy, romantic, and aesthetically attractive atmosphere. Special mention to appreciate Jack (restaurant manager), Chris (host), & Nathaniel (waiter) as together they made sure everything went well for a special dinner. Tonight was celebrating my wife's...

Excellent food, good staff. Setting is good but Unfortunately a little too calm most of the times. I would go again though.

We usually shy away from hotel restaurants but the kids were tired and so were we, so we wanted a simple dinner. We were very pleased. The oysters were local, fresh and delicious and the steak was perfectly cooked. My 12 year old devoured his French Onion Soup and our picky 9 year old enjoyed her homemade mac and cheese.... More

If you are a steak lover like me, you will savor and remember the Octagon at the Mystic Marriott Hotel and Spa in Groton, CT. Exit 88 on I-95 North. My favorite since 2001 is the Octagon Ribeye. It's dry rubbed, grilled and cooked to your liking. Juicy and flavorable.

Octagon is located inside the Mystic Marriott Hotel and Spa. It has a nice menu and is a go to place for locals to meet for drinks. The bar area is smaller but decent for a hotel and the dining room is good size. Prices are average and the food was very good.

They have great steak for dinner but what I prefer is the breakfast buffet. We always take it brunch so our next meal is early dinner.

Stopped in for dinner as we were staying at the Marriott for the weekend. Nathaniel was our waiter and was great. We shared a bottle of wine from local winery Jonathan Edwards. It was eight Chardonnay and was delicious. We both started with Caesar Salad with anchovies (optional). I had the Stonington scallops with a delicious mushroom risotto. It was... More

We were staying at the Mystic Marriott and decided to dine at their restaurant. We had a reservation and arrived a little early and were seated immediately. We sat in a nice 'banquette'. Our server, Jessica was very sweet. I had a surf and turf chowder to start- unusual and very tasty. My husband had a salad which he liked.... More

This is a nice place to stop off for a nice lunch. Even though in a hotel, the food is perfectly prepared and the service is great.
