My husband and I go out to dinner often - at least two or three times a week sometimes more. Never occurred to us to go to Octagon at the Marriott as there are so many excellent restaurants in Mystic and Westerly but today in the spirit of restaurant week we decided to give it a try. We won't be... More

Just had the best birthday dinner ever! I've been to the Octagon several times for breakfast but never for dinner until today. The crab cake was the best I've ever had (and I lived in Maryland for many years) while the scallops with mushroom risotto were equally fantastic! Service was also great (thanks Tom!) and the ambience, comfortable and relaxing.... More

There was a time when the Octagon first opened that it was excellent and exceptional. Then, they seem to have lost some of that initial spark. Well, they have found it again. They have great specials and have adopted a seasonal menu. The champagne dressed chopped salad is great and the quality of the meat is once again superb. Don't... More

We all thoroughly enjoyed our meals and our waitress, Lauren, was attentive, efficient and fun. The filet mignon, as always, was delicious and the lobster mac and cheese was very good

We stayed at the hotel and after traveling for a couple of hours arrived and stopped for breakfast. Although they have a great buffet, we ordered off the menu. We got exactly what we wanted and were extremely satisfied. The staff made us feel like we were family. Thank you!

Let me start by saying I am from Charleston, SC. One of the finest places for fine food and dining experiences. The Octagon restaurant exceeded my expectations. Tom, Roger, and Maria provided impeccable service. My table dined on the lobster bisque, crab cakes, scallops, salmon, and new york strip special. All were done to perfection and were delectable. We were... More

If you are an experienced traveler and foodie I would not recommend you try this restaurant, regardless of the other reviews which may be good. I have eaten at the Octagon at least 6 times. The service, food and atmosphere was always superb. When my friend said she was going to be celebrating her 50th birthday at the hotel and... More

My husband and I ate at the Octagon on 10/18/14. It was a Saturday night but the place was not crowded. My husband had the NY Strip steak and lobster tails. The steak was prepared exactly the way he ordered it and he said both were very good. I had the salmon which was fresh and also prepared as ordered.... More

I stayed at the Mystic Marriott and ate in Octagon for two dinners. Both nights the food and service were excellent. The olive tapenade is quite special, especially with the fresh rustic bread (I mixed with butter, but it's also great by itself.) Stonington scallops are a signature dish - excellent with grilled asparagus. The second night I had the... More
