Great food; do not be concerned if your order is #200 & they call # 8...Completely out of order. We were served after #96. Clams, shrimp, & scallops were fresh & fab. BYOB!!

We have eaten here once before and both times we have gotten pretty good meals. My sons fish and chips was good. My fisherman's platter while good consisted of mostly clams. Got two shrimp and two scallops with it. Over all it was good but next time in the area we will try something different.

This is a relatively simple set up with good seafood and the ability to sit outside by the docks over looking the water and boats. It's BYOB and if you are looking for an adult beverage - bring it!

We tried to go to Abbott's Lobster in the rough but it was so crowded that we decided to try Costello's which is just down the road. Hubby had the chilled lobster roll and I had the fried whole clam bellies which were tender and fried to perfection. It was a beautiful afternoon and we sat outside and watched the... More

We went there on a Saturday evening, though the place wasn't particularly busy. No wait to order. We ordered the New England style clam chowder, fried shrimp and fish and chips. The clam chowder had very little clam meat but otherwise was tasty. The shrimp were similar to the frozen, pre-breaded ones you can get at the supermarket and I... More

The clam strips are as fresh as they come and the fried fish the best. This place is really really good and no tot be missed.

Have been here twice in the last two weeks. Both meals were terrific. A couple of things worth noting. Yes, there are a lot of tourists. It is BYOB. The views of Fishers Island Sound are unbeatable! Had the fish and chips meal and it was wonderful. Crispy fish, not greasy and not too much batter. Mom had the lobster... More

Located in a marina at the end of a pier, Costello's is great seafood with a local flare. It's outstanding seafood served in an outdoor setting. Extremely casual dining as you sit at picnic tables, Costello's baked scallops dinner was excellent as were the fried whole clam bellies. I make it a point to stop on every trip to Groton.

I am a loyal patron of CCS. I have enjoyed the ambiance, food and service for years. Tonight we were served a fried corn on the cob that was overcooked and unsightly. We were served another ear that was picture perfect along with the rest of our meal. When I asked for a $1,50 refund, showing the bad corn, no... More
