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.

Great Lunch but rather noisy

We attended a business lunch. The Ceasar Salad was good, although I will never understand why a fancy parmesan crisp on top of the salad rather than a finely shredded parmesan that can be incorporated into every bite is considered better. For the maincourse we had the pan seared salmon with roasted... read more

This is a good restaurant inside the Marriott. Convenient, made to order eggs and other breakfast favorites. For dinner, I would try another restaurant outside the hotel.

Hotel restaurants are not what I usually look to for great meals. However, we were tired of our old same restaurants and decided to give this a try. The first time we made a reservation I didn't know it was located in the Marriott and I almost cancelled but we decided to give it a try and I'm glad we... More

This was our second visit to Octagon and purposely made a detour to dinner there because the food was so extraordinary. Sad to see the restaurant wasn't busy again, perhaps because it is located within a Marriott. The food was wonderful again. I started with the seafood stew which had shrimp, scallops and a broth with lemongrass and cilantro. The... More

The manager, James, is very personable, professional and accommodating beyond expectations. "Good job, James" The waitress, Caitlin, was "all that and more", made it a great night. The chef was mastery in motion. Salads - nice, soups - wow and dinners to rave about!!!! Good job, OCTOGON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Simply put, a sub par steak house for Premium prices. Very noisy with kids packed everywhere. Great for people if you have kids, but would not recommend for couples trying to have a quiet evening. Steak was overcooked, and sides just did not taste high quality. Average cost of about 70 dollars pp for your meal with no Drinks. At... More
